cl prepare --ctags failure with exuberant ctags 5.7

[René Stadler <mail@…>]

Since I switched from Ubuntu Feisty to Gutsy beta (exuberant-ctags 5.6 to 5.7), moap cl prepare --ctags fails for me like so:

$ ~/build/moap/bin/moap cl prepare --ctags

Updating ChangeLog from Bazaar repository.

Finding changes.

Extracting affected tags from source.

KeyError: 'line ctags: Warning: ignoring null tag in GstInspector/GUI.py not a ctags line'

I traced the problem to the different ctags versions. The newer one outputs a warning line like this on stderr:

ctags: Warning: ignoring null tag in test-ctags.py

While this seems that I'm hitting a very very strange bug in ctags, I think moap should ignore this warning message instead of aborting.

[t.i.m@…]

Odd, I have not run into problems with exuberant-ctags and moap in gutsy so far. (But I've enabled ctags in moap only recently, maybe it's been fixed in gutsy)

(In [347]) * moap/util/ctags.py:

Handle ignoring null tag warnings from exuberant ctags. Fixes #275.
