Bug Description

1. It used to work and I used it few days ago. After some update today, it stopped working.
It is always reproducible for all stitching jobs. So it should be easy to fix. I attached a screen shot of the error message.

Can you provide the backtrace from the assert dialog?
Also check the preferences, tab filename: what is set for the "Default project filename:" and "Default output prefix:"

Could you also attach your preferences file (it should be ~/.hugin)? So I can check some more settings by myself.
(But the backtrace is still needed.)

Hopefully, it helps.

The cause is probably that then blender program is not correctly specified in the preferences. (But I can't reproduce it.) To fix this go to Files>Preferences, on tab Programs select "Reset to default" and close dialog with "Ok". Now it should work again. (I will add an additional check for this case.)

(If you still get the error, check that you can run exiftool from a terminal.)

I reset does not work. I just remove .hugin directly. Now it works. Thanks a lot.
