Package: qgit
Severity: important
Version: 2.7-2
Dear maintainers,
The following procedure could crash qgit:
1. clone linux kernel git repository with argument "--depth 1000" to
make a shallow copy
2. invoke qgit inside the repository
3. scroll down the commit list
Backtrace:
Thread 1 "qgit" received signal SIGSEGV, Segmentation fault.
