-- Information about the crash:
I had an issue with subtitlecomposer crashing, as it turned out, whenever I
reached a specific point in the video I was working on.
That crash report was not useful, so I rebuilt subtitlecomposer and its
relevant dependencies with debug symbols. In this first attempt, this changes
the behaviour, causing an assertion immediately upon starting subtitlecomposer,
that I guess is optimized out in a release build:
ASSERT: "last < rowCount(parent)" in file
/var/tmp/portage/dev-qt/qtcore-5.15.12-r1/work/qtbase-everywhere-src-5.15.12/src/corelib/itemmodels/qabstractitemmodel.cpp,
line 2817
How can I find out which database file (I guess) is causing this assertion, to
'fix' that (i.e. probably delete and have it rebuilt)?
Meanwhile, I'll see to rebuild with debug symbols but with a release-equivalent
configuration, i.e. without the assertion(s).
The crash can be reproduced every time.
