This issue appeared when using Hugin and clicking somewhere but I don't remember where exactly. Probably a bug, but it has been solved by deleting the prefs. Thanks a lot!
If it can't reproduced and it is not clear what exactly cause the crash, I'm closing the ticket. If you have more information you can reopen the ticket.
I tried downloading previous versions of Hugin but it's still the same problem, it crashes on start. I have uninstalled and restarted the computer then re-installed but still the same problem. I cannot locate the hugin.xml file I don't know what to do...
I have downloaded the 2018 version and the problem is not there anymore. All previous versions I tired (2011, 2014, 2017) had the problem for me, 2018 works just fine.
