Hi community, I did take over maintenance for this package, since I need it for work. It's my first package here on the AUR, so please be forgiving for any mistakes.

If there is a problem with the checksums, flag the package out-of-date at the top of the page. I'll update the PKGBUILD as soon as possible.

webex-bin 45.2.0.31846-1: Crash in VoicemailService during XML parsing
System Information
  • OS: Manjaro Linux (Kernel 6.8.0-arch1-1)
  • DE: KDE Plasma (Wayland/X11)
  • Mesa: 25.0.5-arch1.1
  • libxml2: 2.10.3
  • Webex Version: 45.2.0.31846-1
Crash Details

Primary crash location: ZN3csf13VMRESTSession20UTF8ToISO88591SecureERKNS_12SecureStringERS1 (libVoicemailService.so + 0x6e6802) - Triggered during XML character encoding conversion (UTF-8 → ISO-8859-1) - Involves libxml2.so.16 (frame 5 in core dumps) - Occurs in both X11 and Wayland sessions

Secondary issues: - Fontconfig matching errors (FcStrCmpIgnoreCase) - Qt XCB/Wayland interaction problems

Reproduction Steps
  1. Launch Webex with either: QT_QPA_PLATFORM=xcb /opt/Webex/bin/CiscoCollabHost or QT_QPA_PLATFORM=wayland /opt/Webex/bin/CiscoCollabHost
  2. Perform voicemail synchronization
  3. Crash occurs within 1 hour
Debug Data
Suggested Fixes
  1. Add XML encoding validation in libVoicemailService: if (!validateUTF8(input)) { throw SecureEncodingException("Invalid UTF-8 sequence"); }
  2. Verify libxml2 compatibility (2.10.3 vs Webex's expected version)
  3. Check fontconfig cache integrity
Additional Context

The crash appears distribution-agnostic, affecting all systems using this AUR package. Full debug symbols would help pinpoint exact failure points in proprietary components.

Let me know if you need additional testing or specific log sections.

I can try to swap bundled Qt5 to get rid of old dependencies if someone tell me what libUIToolkitQml.so is.

@simon42 I'm using Gnome and Wayland, so X11 is not the problem for me. Can you confirm your libxml2 version with pacman -Ss libxml2? Is your Webex version 45.2.0.31846?

Here are some of my error logs. First with libxml2-legacy installed, where Webex crashes: Journalctl: https://pastebin.com/UC8Bcvh2

Webex Crash Info (~/.local/share/Webex/crash_info_*) https://pastebin.com/vEtpHTCS

Without libxml2-legacy, my Webex Log (~/.local/share/Webex/current_log) is filled with errors that libxml2.so.2 is missing: https://pastebin.com/TNRmb22E

So my guess is that we need libxml2-legacy and some other dependencies that we don't know yet. Any ideas are welcome :)

Same problem here with the crash of the Webex client. Did you find a solution for the problem?

I realized that the crash seems to be related to using X11. When I switch from X11 to Wayland, the client does not crash and works as usual (including phone service). I am using KDE Plasma.

@moritzo I have exactly the same problem

moritzo commented on 2025-05-05 15:04 (UTC)

@karamba I just did a pacman -Syu and my Webex client works partly again. I'm still unable to connect to the phone service, though. Can you confirm? Any advice is appreciated! libxml2-legacy did not solve the problem for me, too.

@m1k.cloud I have already tried this without success. The same issue:

pacman -Qo /usr/lib/libxml2.so.2 /usr/lib/libxml2.so.2 is owned by libxml2-legacy 2.13.8-1

@karamaba i'm guessing related to libxml2 breaking change, probably this now needs libxml2-legacy as many other aur packages do

karamba commented on 2025-05-02 10:39 (UTC)

After synchronizing packages this morning 2025-05-02 the Webex app throws segmentation fault after joining to Unified CM with following errors: https://pastebin.com/raw/KEsbPxqy

This issue did not occur until I updated the following package list: https://pastebin.com/raw/4j9h3dkG

For the Problem (blank screen after trying to sign in) that happens on Wayland: run webex using env -u WAYLAND_DISPLAY webex, then you can login and no longer need to launch it using that prefix command. EDIT: i would actually recommend to add env -u WAYLAND_DISPLAY in /usr/share/applications/webex.desktop to always start with that prefix, since some windows that pop up for editing messages don't react if you don't start it with it.
