Bug ID: 157088
Summary: qt6: Crash on exit after using font color toolbox item
with Orca running
Product: LibreOffice
Version: 24.2.0.0 alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: UI
Assignee: [email protected]
Reporter: [email protected]
This is only reproducible when Orca actually announces what's in the UI with
the qt6 VCL plugin, which is currently not always the case (s. step 3)...
Steps to reproduce:
1) start the Orca screen reader
2) start Writer
3) perform actions until Orca starts announcing what's there in the UI
(clicking around etc. often helps, or pressing F1 without local help being
installed to open a dialog box asking whether to go to the online help)
4) press F6 until the formatting toolbar is focused
5) press Tab until the Font Color toolbox item is focused
6) press Space key to open the toolbar popup
7) press Tab twice to move to the list of colors, then move around using the
arrow keys
8) press Tab again to move to the recent color list, more around there
9) press Esc to close the toolbar popup
10) close Writer
Note: Make sure that Orca announces the colors in steps 7/8.
Result: LO crashes with the below backtrace
