Hi, are there any follow-up fixes on the issue. I followed the workaround to force x11 session for login then switch back to normal wayland session afterward to avoid the crash. However, on the wayland session, whenever I try to reply/edit a message or start a thread. Webex always show black screen which prevent me from further using the app.
FYI, here is my system information:
For the "blank screen after trying to login" problem on wayland: using env -u WAYLAND_DISPLAY didn't help in my case - webex was still running in wayland. But using env QT_QPA_PLATFORM=xcb to force x11 for a QT application fixed it for me.
@moritzo: pacman shows core/libxml2 2.14.2-2 and further extra/libxml2-legacy 2.13.8-1
Webex version is 45.2.0.31846 ("Help > About" section of the client), yes.
I get the same crash via libxml2 that you reported and the same core dumps reported by @dasarne, but only when running the client with X11. According to my logs, it must be something libxml2-related, I agree.
Still, when running with Wayland, the client does not crash for me, I can call others, I can use the voice mail service and so on. The client is running for hours now without any crash. I observed the same behavior on another machine, so it is kind of "reproducible" at least on the configuration(s) I am using. Really strange.
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
journalctl logs available on requestldd output shows no missing dependencieslibVoicemailService:
if (!validateUTF8(input)) {
throw SecureEncodingException("Invalid UTF-8 sequence");
}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
@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

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.
