Package: libqt5webenginecore5
Version: 5.15.2+dfsg-3
Severity: important
X-Debbugs-Cc: karogyoker2+deb...@gmail.com
Dear Maintainer,
I tried to start Konqueror on a fresh install of Debian by typing konqueror
into LXTerminal, it doesn't start, just crashes all the time.
It violates the i386 baseline by using SSE2 unconditionally, even if the host
CPU doesn't support it (tested on a downclocked Athlon XP).
I suggest that https://wiki.debian.org/SIMDEverywhere might be helpful in
developing a patch, if it isn't just a compiler flag fix.
If this issue/bug is unfixable, the package should depend on package
sse2-support (i386 only).
It crashes right after start and produces the below stack trace:
Application: Konqueror (konqueror), signal: Illegal instruction
