To avoid crashs when opening PDF's, and hangout on exit install mendeleydesktop-bundled which packages Qt provided by the upstream.

@David01 I'm busy this week so I'll try to fix the problem during the weekend.

@akstrfn I have added export LD_LIBRARY_PATH=/opt/mendeleydesktop/lib/qt to ~/.bashrc and sourced it. No successful results:

[david@david-pc ~]$ mendeleydesktop

I don't know if I upgraded the system or did something, but suddenly I couldn't launch Mendeley Desktop. Some issues with the QT library.

In order to use Mendeley again, I have to manually set the runtime QT5 library path to the one included in this bundle, i.e.,

$ export LD_LIBRARY_PATH=/opt/mendeleydesktop/lib/qt

But I don't recall I had to do manually set the path before.

After the latest update, mendeleydektop doesn't work:

Running mendeleydesktop on the terminal yields:

qt5ct: using qt5ct plugin
QFSFileEngine::open: No file name specified

/usr/bin/mendeleydesktop: line 4:  1642 Trace/breakpoint trap   (core dumped) /opt/mendeleydesktop/lib/mendeleydesktop/libexec/mendeleydesktop.x86_64 "$@"

It doesn't quit properly. When the GUI closes, the process keeps running and its CPU usage flies to 100%. There is a 1.19.5 version released by the upstream and they say some bugs are fixed. Any update plan?

Thanks. Fixed.

There may be a slight bug in the install-mendeley-link-handler.sh script (https://forum.manjaro.org/t/mendeley-aur-and-ld-library-errors/75931).

This should do the job:

diff --git a/PKGBUILD b/PKGBUILD
index 69ac243..80f8510 100644
--- a/PKGBUILD

     install -d "$pkgdir/opt/$pkgbase"
     cp -a bin lib share "$pkgdir/opt/$pkgbase/"

It won't replace an existing mendeleydesktop.desktop file but it will help for new users.

Please change line78 of PKGBUILD to:

sed -i 's/Exec=/&env LD_LIBRARY_PATH=\/opt\/mendeleydesktop\/lib\/mendeleydesktop\/plugins\/platforms /' bin/install-mendeley-link-handler.sh

in order to stop ld_library path errors

Your whole system does not look healthy...

I'm on an updated 64bit Arch and I'm experiencing frequent Gnome-shell (in libgnome-shell.so) crashes while doing various actions in mendeleydesktop-bundled. Usually this happens when I add a new PDF or when I try to export to a .bib file.

Here the log of the last crash: https://paste.fedoraproject.org/paste/9kk58ZfiICU89QeUUWrumQ
