[galaxy-dev] error running cuffdiff

Hi there

I'm running into this error with cuffdiff:

​​​​ I'm running galaxy locally on a cluster (1 head+3 compute nodes) with MySQL. Here's my hg summary:

​ Any clues?

I also keep getting the a similar 149 Internal Server error (with different Key Error) thrown when trying to install some tools. But strangely, after leaving it for awhile, it went back to normal. So I'm not too sure what's causing it.

Should I be updating galaxy to the latest stable one?

Please let me know if you require any other info.

Thanks!
