I was viewing a layer when qrecall crashed.
Thanks for the crash log, Steve.
I can't reproduce this problem, but I made the code a little more bullet proof so it shouldn't happen again (in the next version, obviously).
Is the crash reproducible or was it a one-time occurrence?
Also, if you have a crash report you might find it easier to simply send a diagnostic report. The Help > Send Report command gathers up all QRecall related crash logs and includes them in the upload.
