Hello,
I don't deny you have an issue, but setting the flag critical for an
issue you have with the package in stable may be a little bit much?
The bug also flags the package for autoremoval in testing...
Concerning your issue, can you be more specific on the problems?
I'm using motion for a long time myself and I never had such problems.
Maybe you can look at your system configuration, for example if you save
the files on a remote location that could lead to files lock issues?
If the problem doesn't come from the package itself, we'll transfer it
upstream then.
