hum i don't understand...

in konsole, i have much line of errors for example :

and at the end, i have :

Sorry for the delay, I can confirm the bug in the current cauldron. There are various missing dependencies and likely other issues, will work on fixing it.

Thanks for the report, there were two missing dependencies (though the above errors don't show it very clearly at a first glance):
- python-numpy
- python-gi-cairo

mypaint-1.2.0-2.mga6 should now start fine. Could you test and confirm?

Hello, 
it's all right ! 
my paint works very well in Mga-Stat 1
Thanks Rémi

this is not a bug

Resolution: (none) => FIXED
Status: NEW => RESOLVED
