Hi, what versions of OS and Onboard are you running? Is that Ubuntu Saucy by chance?

Is this on a mobile device (ARM) or x86 system?

Hi. I don't know what I was thinking, not appending any sys info. The system is a x86 Notebook (Thinkpad x230t actually) and the system is indeed Saucy.

Thank you. Onboard trunk crashes too on Saucy, unfortunately, Francesco reported as much already. His backtrace looks different, though. He noted an odd version mismatch between python3 and libpython3. I'll have a closer look tomorrow.

Fixed in trunk. Python thread state wasn't properly set up, and Python 3.3.2 added a recursion check that relied on it. The version mismatch wasn't at fault.

Hi,

I have uploaded a snapshot of the current development status of Onboard containing a fix for this bug and other new features to our main PPA:
https://launchpad.net/~onboard/+archive/ppa

The snapshot is available for raring and for saucy.

Have a nice day.
