Bug#1027690: lmms: Segfault on startup with kwidgetsaddons 5.101.0
Package: lmms
Version: 1.2.2+dfsg1-4+b3
Severity: grave
Tags: patch upstream
Justification: renders package unusable
Forwarded: https://github.com/LMMS/lmms/issues/6587
Dear Maintainer,
LMMS experiences a segmentation fault on startup. According to an
upstream bug report [1], this appears to be due to a specific workaround
for an old bug in KXMLGUI [2], which breaks with kwidgetsaddons 5.101.0.
As the comments on the upstream bug report suggest, a workaround is to
downgrade kwidgetsaddons to 5.100.0. I can confirm that downgrading the
libkf5widgetsaddons5 and libkf5widgetsaddons-data packages works on my
system.
The fix for this segmentation fault is to remove the workaround [3], as
the KXMLGUI bug has been fixed for some time (since version 5.55.0).
