Hello Bernhard,

I was able to reproduce and to get a backtrace, which I attached to this
email.

I tried clearing out the ~/.config/midori/ directory. After doing so, I
no longer get a crash when selecting the "About" menu option.

If needed, I can try to recover the bad config from backups, for the
sake of testing future versions of Midori and GNOME Shell.

Thanks, : )
