Hi all,
I've been unable to run Rosegarden for a while, as it segfaults when
launched.
System:
Ubuntu 10.04 LTS
Linux zaphod 3.1.4 #1 SMP PREEMPT Sat Dec 3 12:02:09 NZDT 2011 x86_64
GNU/Linux
Dual Opteron 244, 6 GiB RAM, Iwill DK8N (nForce3 250Gb + AMD 8131)
Echo AudioFire12 (Firewire audio + MIDI I/O)
Rosegarden is version 11.11.11 built from source:
$ rosegarden --version
Rosegarden version: 11.11.11 ("Edelweiss")
Build key: c2026ea19c
Built against Qt version: 4.6.2
(It also happens with the Ubuntu Rosegarden package I have; version
details below:
$ /usr/bin/rosegarden --version
Rosegarden version: 10.02 ("Thorn")
Build key: 651014598d
Built against Qt version: 4.6.1)
Detailed description: every time I attempt to run Rosegarden, it
segfaults. The splash screen appears, says "Initializing plugin
manager..." and then "Initializing view...", then it quits out with a
"Segmentation fault" error.
It will launch without the segfault when run as "rosegarden
--nosequencer", but my MIDI interface is built into my AudioFire, so
JACK MIDI via FFADO is my only MIDI I/O option at the moment.
Running in gdb gives the following information and stack trace:
Program received signal SIGSEGV, Segmentation fault.

I wondered if it might be a problem with unusually-named LADSPA plugins,
so I also tried unsetting LADSPA_PATH (`export LADSPA_PATH=`) before
running, and checked that `listplugins` listed no plugins, but it made
no difference.
Thanks for any help you can offer,
Chris
