Code completion freezes C::B 12.11 on Ubuntu13.04

[headphones54321]

Hello,
I'm using ubuntu 13.04 64bit and code completion is causing a complete freeze of C::B.

There are a couple of interesting things to note about the behaviour:
1) I used C::B 12.11 for an entire day without issue, then it started freezing and it seems to be permanent.
2) I can open the project and browse around all the libraries, but as soon as I select the tab with the main function in it - frozen. I don't even get a cursor.

I tried reinstall from scratch, and deleting ~/.codeblocks but it keeps doing it.

Is there a setting I can try to resolve this? If not, can I help debug in anyway?

I really like the code completion feature, it's very handy.

Thanks.

Are there any crash report? See: 12 Q: How do I report a compilation problem on the forums?

If CC crashes, it mostly have some bugs in its parser.
I'm not sure you if you can supply your source file (or a minimal example), then I can test it.
