[Bug 944053] [NEW] rabbitvcs stalls

[axeoth]

Public bug reported:

When launching (Xubuntu 12.04 updated) "rabbitvcs log" on terminal
prompt, in home folder (that is, no SVN and no GIT working copy), the
following message is displayed:

** WARNING **: Trying to register gtype 'GMountMountFlags' as enum when
in fact it is of type 'GFlags'

** WARNING **: Trying to register gtype 'GDriveStartFlags' as enum when in fact it is of type 'GFlags'
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/rabbitvcs/ui/log.py", line 1462, in <module>
    window = log_factory(paths[0], vcs=options.vcs)
  File "/usr/lib/pymodules/python2.7/rabbitvcs/ui/log.py", line 1446, in log_factory
    return classes_map[vcs](path)
KeyError: 'unknown'

Then, it simply stalls. No window, no prompt, nothing.

Fortunately, CTRL+C allows recovering prompt in terminal.

When typing "rabbitvcs log" in a terminal window inside a directory
containing a SVN working copy, it displays:

** WARNING **: Trying to register gtype 'GMountMountFlags' as enum when
in fact it is of type 'GFlags'

** WARNING **: Trying to register gtype 'GDriveStartFlags' as enum when
in fact it is of type 'GFlags'

but eventually, it opens the rabbitvcs (log) window and displays the
log.  However, after closing that window from the "x" button, the prompt
is not recovered, and pressing "CTRL+C" is needed in order to retrieve
it.

Finally, the rabbitvcs (log) window, while displayed, is not fully
functional. For example, trying to launch "Compare with previous
version" for a file changed with one commit, will result in displaying
no (meld) window, but instead in displaying (inside the terminal) the
following:

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/rabbitvcs/ui/log.py", line 1296, in compare_previous_revision
    if len(self.revisions[0]["parents"]) > 0:
TypeError: object of type 'NoneType' has no len()

Thank you.
