SUMMARY okular crashes when opening a menu if invoked from auctex STEPS TO REPRODUCE 1. install emacs and auctex. 2. create some .tex file, compile and view via command. Then the command is shown. It is something like okular -unique template.pdf#src:74./template.tex 3. press return and observe okular comes up correctly. 4. try to press a menu entry: crash OBSERVED RESULT crash as described above EXPECTED RESULT show the content of menu. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Very interesting: if invoked from command line, that crash does not occur. Even if then that command is invoked from auctex, (e.g. to view another line) that problem disappeared. Note that auctex seemed to have changed sth: no master directory any more. This bug seems new, either in side of auctex or of okular.
Could you give us the backtrace you get? The crash dialog should give it to you, if not tell us and I'll try to give you the commands to get it via gdb

Ok, then just run okular the way you make it crash, but before making it crash, open a terminal become root and type gdb attach `pidof okular` once you end up inside the gdb terminal type "continue" and press enter now make it crash once it crashed type "bt" and then enter and attach the information here
I tried but it requires `zypper install okular-debuginfo-20.04.0-1.1.x86_64` maybe i must configure a repo for that because cannot find.
can't really help you with opensuse questions, sorry :/

You need to enable the debug repo first. (it should be preconfigured by default but disabled, if necessary you can find the URL here though: https://en.opensuse.org/openSUSE:Tumbleweed_upgrade#Repositories ) Or use this zypper command instead: zypper --plus-content debug install okular-debuginfo
I have new information: 13:44 $ gdb attach `pidof okular` Excess command line arguments ignored. (13399 ...) GNU gdb (GDB; openSUSE Tumbleweed) 8.3.1 Copyright (C) 2019 Free Software Foundation, Inc.

Further info: has nothing to do with auctex, just with emacs. Still further hint: Emacs is a bit command line. One can make it display the command it issues. It is sth like `okular -unique recon.pdf#src:7./recon.tex`. Strange enough, if i do that on a shell, all is ok. So it must have sth to do with emacs...
This is really weird, can you try installing the debug info for libqxcb-glx-integration.so if opensuse has it?
