DescriptionI got the following bug for vcmi 0.98 on the Debian bug tracker which I'm also to reproduce myself:

Just in case attached full crash log from 6c33417 (0.98 release).
It's about the same (with different line numbers) on develop.

Sadly I didn't manage to find out why that happen, but it's reproducible up to current git.

We talked about this, and came to the conclusion that broken saves are to blame.
If you install the new version and start playing now, and try to capture the city, then everything will be fine.
At least I did it under Windows many times and it didn't crash.
