-- Information about the crash:
Unpacked the archive partially (via Ark), canceled the unpack, tried to delete
the folder, crashed every time as I tried. I experienced same behavior before,
and both of times when files are created with size, less than full (partial
created files that grow in size), both ways to fix - as I remember or restart
the Dolphin, or restart the whole system.
(sorry but I was curious and) Claude concluded that it's handler of the file
size (weird since how I can delete the big files then? nvm, tested and I still
can't delete big files before reboot, nor 6+ GB file, nor folder that contains
it, but can delete folder with smaller file), cite:
The crash occurred in KDE's Trash system when trying to move a file to trash.
Specifically:
The problem (line #16-18):
qCheckedFPConversionToInteger<int, double>(value=6704756736.5)
qRound(d=6704756736)
TrashImpl::adaptTrashSize
Root cause: The trash implementation tried to convert a very large file size
(6704756736.5 bytes ≈ 6.7 GB) from a double to an int, which caused an integer
overflow.
int maximum value is ~2.1 billion (2,147,483,647)
The file size was 6.7 billion bytes
This triggered Qt's assertion check and crashed the program
What was happening:
You were moving a file to trash (line #20: TrashImpl::moveToTrash)
The system was trying to update the trash size metadata (line #18:
adaptTrashSize)
It tried to round a file size that was too large to fit in a 32-bit integer
Qt detected the overflow and aborted to prevent corruption
The crash can be reproduced every time.
