Package: libqt5core5t64
Version: 5.15.15+dfsg-2
Severity: normal
X-Debbugs-Cc: fenix...@gmail.com
Dear Maintainer,
* What led up to the situation?
Opening a file browser in an app (I tested two: Krita and VLC)
causes the process to reach 100% CPU usage, freezing the app. After
trying to open a file browser again, the app eventually crashes.
Steps to reproduce:
1) Open VLC.
2) Select "Open new file".
3) While the file dialog popup is opening, the process reach 100% of CPU
(check with top) and VLC freeze.
4) Close the file browser popup.
5) Try opening a file again.
6) This time, the app crash pass a time.
This is part ot the coredump crash information:
