hi, so i took this month to study krita for real and make it my main drawing app..and i love it. thanks so much for such an amazing software!

i've noticed some quirks, it tends to get unstable and crash a lot after operations involving duplicate of open files and/or exporting.
my question is how do i get to know if the bugs are known to you guys, and how to report the ones i find?

*incidentally, i got a prompt to submit a bug report after a crash today, but only this once, and it told me the info gathered was not good enough...
krita 2.9.11
ubuntu studio 14.04

Make sure you install the corresponding debug packages, too. Those will make the backtraces useful. However, we're now focusing on getting 3.0 out and that means that bug reports for 2.9 might be less useful since a lot of code got rewritten between 2.9 and 3.0.
