Comment 2 for bug 810569

Hi - I seem to have found the same bug. Here is my experience with it:

I am new to Ubuntu Studio having installed it as a dual boot capability on my Dell 1555 computer about 3 weeks ago. I am using the 64 bit version. This is my first experience with Linux and so far I like it. I have had some successes using Ubuntu Studio. In the last 3 weeks, I have figured out how to use Jack at least well enough to make Pianoteq (Linux version), QSynth, Rosegarden, and Ardour work on my computer. I have also been successful in connecting my midi keyboard to my computer and it is working well with Pianoteq through Jack.

I have installed Swami on my machine using the Ubuntu Software Center and when I try to run it, it says it is starting up in the panel bar, but then it just disappears and does not run. Note I started Jack before running Swami. In my searching, I was inspired to try to run Swami in a terminal window. I received the following text:

libswami-Message: Loading plugins from /usr/lib/swami
libswami-Message: Loaded 4 plugins
JackActivationCount::Signal value = 0 ref = 3
JackActivationCount::Signal value = 0 ref = 3
JackActivationCount::Signal value = 0 ref = 3

(swami:2759): libInstPatch-CRITICAL **: ipatch_type_get_valist: assertion `type != 0' failed
Segmentation fault

This error looks very similar to this bug report.
