Yes. Thanks.
The first line relevant to rg is this:
#19 0x0000555555e3188e in Rosegarden::LADSPAPluginFactory::loadLibrary
(this=0x7fffb0004fd0, soName=...)
at
/home/rainer/Downloads/rosegarden/src/sound/LADSPAPluginFactory.cpp:504
And this is not unusual. Unfortunately, if there are problems with
plugins, rg does little to protect itself against them crashing. We
have a bug on our bug tracker related to this:
https://sourceforge.net/p/rosegarden/bugs/1474/
Not sure anyone will get around to fixing it, though. And
regardless, we can't really fix this issue. The problem is actually in
the fluidsynth-dssi.so plugin that we are trying to load:
#8 _dl_new_object (realname=realname@entry=0x7fffb014e0a0
"/usr/lib/dssi/fluidsynth-dssi.so", libname=libname@entry=0x7fffb0153ab8
"/usr/lib/dssi/fluidsynth-dssi.so",
type=type@entry=2, loader=loader@entry=0x0,
mode=mode@entry=-1879048190, nsid=nsid@entry=0) at dl-object.c:89
So fluidsynth's dssi plugin is the next place to look. Of course,
once again, the issue might actually be caused by something fluidsynth
brings in.
BTW, this error only occurs on my laptop running Debian bookworm.
On my (dual boot) desktop, rosegarden works fine both under KDE neon
and EndeavourOS, using pipewire 0.3.48.
Not surprising. Could be a config difference, or something subtle
about library versioning.
I'm going to add some logging to help diagnose this in the future.
This isn't the first time this has been an issue. It would be nice to
know exactly what is going on immediately.
Thanks for the bug report.
