[LAU] MusE problems

Hi MusE is the center of my setup but unfortunately the current ubuntu binary refuses to load any of my old *.meds, prefering to crash instead (0.8.1). I decided to try and build a newer MusE from source but I've had no luck there either. uic from qt3 just segfaults when used. ie: /usr/share/qt3/bin/uic -L ../../muse/widgets -o organguibase.cpp -impl organguibase.h organguibase.ui make[5]: *** [organguibase.lo] Segmentation fault I've tried v0.9 and 1.0rc1 to the same effect. a backtrace reveals little (to me): #0 0xb7d6e48c in QMutex::lock () from /usr/share/qt3/lib/libqt-mt.so.3 #1 0xb5fdfda0 in QAbstractFileEngineHandler::QAbstractFileEngineHandler () from /usr/lib/libQtCore.so.4 #2 0xb600acb7 in ??

Has anyone managed to build MusE on intrepid? pete.
