I think I fixed that part, as the mutex works as expected now, (see the latest midimapping.cpp in trunk) but when dlgprefmidibindings tries to operate on the returned QList pointer (to see if it's empty, for example) it segfaults because the returned pointer is not always valid. (Sometimes it's 0x1c, 0x26, or a 32-bit value which half of the time isn't valid either.) When it does happen to be valid, it segfaults when I try to modify the QList (with takeFirst()). So is this the same problem? If so, how do I figure out how to fix it? This memory management stuff is killing me.
