Description Jouni Rinne 2009-12-06 22:22:58 UTC

I haven't had time to do much testing, except that it segfaults on both x86 and amd64. According to Rosegarden forums ( http://old.nabble.com/First-try---qt-4.6---not-good-td26637036.html ) the segfault is triggered by bug in qt-4.6.0; so we probably need to wait for either rosegarden-alpha3 or qt-4.6.1 (or backport the patches...)

But the bug in Qt4 remains, so moving to Qt4 maintainers

This bug is supposed to be fixed in the upcoming 4.6.1 release.
