Version: 6.2.0.0.alpha0+ Build ID: f7c37579e6c348ec8d48ddbfb26e08ac09a8eeba CPU threads: 4; OS: Linux 4.17; UI render: default; VCL: gtk3_kde5; Locale: en-GB (en_GB.UTF-8); Calc: threaded Steps to reproduce: 1) start LibreOffice Writer with the "gtk3_kde5" VCL plugin, command: SAL_USE_VCLPLUGIN=gtk3_kde5 ./instdir/program/soffice --writer 2) Save the document using "File" -> "Save as" 3) repeat step 2, changing file name and storage location, until the issue appears (Unfortunately, I haven't found any better steps to reliably trigger the issue yet.) Result: At some point in time, the "Save as" dialog disappears, but the window showing the document is unresponsive, appears "freezed". Looking at running processes on the system reveals that "instdir/program/lo_kde5filepicker" is still running (which is probably also the reason why the main UI is "frozen").
Created attachment 144655 [details] GDB backtrace of the state when the UI is "freezed"
Some Linux distros confirm e.g. https://bugs.archlinux.org/task/59839 https://bugs.gentoo.org/657236 but IDK if that is a sufficient condition to set the bug to confirmed here as well
Xisco: considering these elements: - we got a bt from Michael - Michael worked on this part (see https://cgit.freedesktop.org/libreoffice/core/commit/?id=f971bdb026735fdecd777d0d2edc515124f9e822) and so knows what he's talking about - bugs reported from external bugtrackers quoted by Katarina - perhaps very few people use gtk3-kde5 since quite recent so less feedback would it be ok to set the status to NEW here even if nobody has confirmed yet?
A single other confirmation is enough -> NEW
I'm currently trying to further analyze this.
