I have crashes with 7.3+ master in Linux GTK3, seems when changing Enable experimental features. Message on console is "Attempting to add a widget with type GtkBox to a GtkToolItem, but as a GtkBin subclass a GtkToolItem can only contain one widget at a time; it already contains a widget of type GtkComboBoxText". I also see " gtk_notebook_get_tab_label: assertion 'list != NULL' failed" but it doesn't seem to be directly before the crash. Steps (possible): Open DOCX attachment 62191 [details] from bug 50447 Tools-Options-Advanced: turn on or off Experimental features Restart now cannot start LO. OR if LO starts, crashes on next click on Tools-Options-Advanced Try also to turn on Manage Changes in Sidebar (as Experimental feature).
On pc Debian x86-64 with master sources updated today with gtk3 rendering + experimental features enabled, I don't reproduce this. Would it be possible you retrieve a backtrace? (see https://wiki.documentfoundation.org/QA/BugReport/Debug_Information#GNU.2FLinux:_How_to_get_a_backtrace)
Crash also happens after removing profile, without open document, just with going to Open Expert Configuration.
Which locale do you use? Did you succeed in retrieving a backtrace? I gave a new try but still no crash or assertion. About "Attempting to add a widget with type GtkBox to a GtkToolItem, but as a GtkBin subclass a GtkToolItem can only contain one widget at a time; it already contains a widget of type GtkComboBoxText", it's been fixed with https://cgit.freedesktop.org/libreoffice/core/commit/?id=033dbb01f0688610338c80136ed73f2b412397ec author Caolán McNamara <caolanm@redhat.com> 2021-08-17 14:59:32 +0100 committer Caolán McNamara <caolanm@redhat.com> 2021-08-18 10:35:10 +0200 commit 033dbb01f0688610338c80136ed73f2b412397ec (patch) tree c93b483616a56cbc97d7495931846b9a00286fc2 parent 686528f3281ce60c1d5c12cb867b2b16081444af (diff) gtk3: fix warning about GtkBin already containing a widget
I cannot reproduce with Version: 7.4.0.0.alpha0+ / LibreOffice Community Build ID: 571be264d9604c3d77036e26812f909655cc0bb2 CPU threads: 4; OS: Linux 5.11; UI render: default; VCL: gtk3 Locale: cs-CZ (cs_CZ.UTF-8); UI: en-US Calc: threaded Jumbo Timur, can you retest? Thank you.
I don't repro now.
