You're not allowed to perform non-rt-safe operations like pthread_mutex_lock() in the jack process callback.
However, it appears the buffer implementation read from the LMMS Jack process callback does cause pthread_mutex_lock() calls:

#4 0xb72b71b0 in QWaitCondition::wakeAll() () from...

You're not allowed to perform non-rt-safe operations like malloc() in the jack process callback.
However, it appears the QT constructs used in the LMMS Jack process callback do cause malloc() calls:

The names for the 2 MIDI-related tabs in the 'Connect' window are confusing.
The JACK MIDI tab is called 'MIDI', whereas the ALSA MIDI tab is called 'ALSA'. I'd propose altering src/qjackctlConnectionsForm.ui to rename those tabs to 'JACK MIDI' and 'ALSA MIDI'.

Sorry about the noise - looks like this was already fixed between 0.3.4 (which comes with Ubuntu Karmic) and latest SVN.

looks like 'autoheader ; autoconf' does the trick.

probably simple, but it'd be nice if this was documented somewhere.

when a port is renamed (jack_port_set_name), qjackctl will keep showing the old name, even after 'refresh'.

The current code assumes channel names will not be longer than 9 characters, which is wrong.
Attached is a patch that, among other small cleanups, replaces this assumption with the assumption that interface->channels[c].label will not be freed. Someone will need to review that assumption - if it does not hold, a strdup() could fix that.

When jackmixdesk is running, jackmixdesk_gtk crashes on startup (built from SVN)
