Martin Peach, I read somewhere that changing pages in TouchOSC makes Pd (or Pd-Ext) to crash. My Pd-Extended doesn't crash, but this error is shown: "* routeOSC: ignoring empty list...".
Today, I've installed Ubuntu Studio 12.04.3 (with lowlatency kernel). It seemed that it was a good distro for my use... but switching pages DOES make Pd-Extended to crash. I reported-suggested this in this thread: http://hexler.net/forum/viewthread/992/, where I wrote some other info, maybe usefull.
The config where it doesn't crash:
/Ubuntu 12.04, Kernel 3.2.0-49-generic, Pd-Extended 0.43.4 (download from PPA as the Pure Data page says), jackdmp 1.9.8...// / The other config:
/Ubuntu Studio 12.04.3, Kernel 3.2.0-51-lowlatency, same Pd-Extended version, Jack that came with UbuntuStudio (don't know wich version)/
Any other information that could be useful to fix this? Like I wrote in the thread, I suggested TouchOSC that it should send non-empty lists. But, TouchOSC is closed-code... so, there's no easy feedback.
