--- Comment #7 from Postix <pos...@posteo.eu> --- Created attachment 125427 --> https://bugs.kde.org/attachment.cgi?id=125427&action=edit gdb stacktrace (In reply to Albert Astals Cid from comment #6) > "thread apply all bt" in gdb > Also ideally do that before closing I tried it again, this time with a debug build of Okular and the qt-debug packages on Manjaro Unstable in a virtual machine. Also glibc-debug was installed, but it still seems to lack the debug symbols. What did I do? 1) Started Okular with gdb gdb okular gdb run 2) Loaded a troublesome PDF and started scrolling until the CPU went high and no more - not yet rendered - pages were loaded 3) Interrupted the process in the terminal by ctrl+c 4) Generated the backtrace via thread apply all bt full which is now attached and hopefully more useful to you now. If not, please tell what I should do instead or additionally of steps 1) to 4). :) > Also if you have a file in which it's relatively easy to reproduce, attach it With 17 MB it's too big to attach it here. Maybe I can send it to you via mail? -- You are receiving this mail because: You are the assignee for the bug.
