[Freevo-devel] [Patch] Freevo 2.0 record server crashes

[Michael Sharman]

Hi, I've been playing around with the latest svn Freevo 2.0 of late to see if I can help out with the recording/live tv development work; on my machine I get the following error when attempting to run the test kaa/record/test/recorder.py, I've created a patch that fixes a memory corruption problem in the C++ extension code, see attached.

I hope this is the right place to report kaa bugs?

Keep up the good work,

Michael

This is what I get without the patch:
