Description Jaime Torres 2013-07-06 07:35:45 UTC 
The fraces scan finished long time ago..
I was seeing the unknown faces list, introducing names to the faces..
In one photo, there were 2 faces. One was detected, the other one not.
I manually added the not detected face, introduced both names (without pressing confirm).
Then I pressed confirm in both of them quickly (once you confirm a face name, the photo dissapears from unknown faces list), perhaps when the photo was changing to the next one in the list..And crash.

I've just noticed: 89 threads....

Reproducible: Sometimes




I could not use drkonki (too much information... perhaps the backtrace of 89 threads).
Comment 1 Jaime Torres 2013-07-06 09:01:17 UTC 
I've just noticed that before the crash, the dialogs to introduce the name behave randomly...
They do not move to allow you to select the name from the list, so the list is bellow the low border.
They move so you can not click on them to select the name.
They stay calm, but you have to select the name several times, because it is discarded.
In a image with several recognized faces, name one, the image is reloaded and you can enter more names. At some moment, this changes and you can only enter the first one unless you click on another image and back to the desired one.

This means I can reproduce this bug.

In fact the trace is the same than bug #262596
