Interface does not open on repository with large number (>50k) of tags
The Haiku project uses git tags to maintain a monotonically increasing revision number inherited from svn. The main repository is now at hrev53001.
Trying to run gitg on a checkout just hogs the CPU for more than 10 minutes without opening any window.
Note: for testing do not clone from github but from the official repository, since tags are not imported to github (for the same performance reasons).
