I get a seg fault every time I try to save my preference.

This happens on Fedora 17, 18 and 19 with versions 1.7.4, 1.8.3 and 1.8.4.

Whilst I would love to have a fix for this, if anyone can tell me how to manually set up the min title length that would make me happy.

Back trace from the sigsev is as follows.

Fabulous, that gets me the workaround I need.

Thanks.

Thanks for the work around and I can confirm that it's good. Will this be fixed though in the next version release?

I had similar problems (segfault on attempting to save preferences) on Fedora. I thought it was SELinux or any variety of other things.

By any chance, are you using an RPM package that you may have made from someone else's .spec file? I had tried all sorts of things short of compiling directly on my target machine. Same results until I noticed that there were a few files that were not getting placed "correctly" compared to the install from source (on Ubuntu). So I updated an earlier (1.7.9?) .spec file and started with that and updated it for 1.8.4 and it compiles cleanly on both Fedora 18 and 19. rpmlint is also clean.

I can't say my updated .spec is perfect (it was really my first attempt at packaging), but I do not have segfaults any more. I am willing to share it. (Since this is my first post, I don't know the etiquette here. Is it post .spec in a public message or in a PM?)
