Segmentation fault when selecting link

[Lorenzo Miniero]

If I navigate to a diary page containing a link, and using the mouse select the text containing the url starting from the end, lifeograph crashes with a segmentation fault. I can replicate this consistently, on the lifeograph shipped in the Fedora repos (1.5.1.1).

This is the trace I could retrieve with gdb:

Thread 1 "lifeograph" received signal SIGSEGV, Segmentation fault.

Please let me know if there's anything else I can provide for tracking this issue, or if this has indeed been already solved in master.

[Ahmet Öztürk (dmxe)]

I can replicate it in v1.5 but not in v1.6. So, marking as fix released. Please upgrade your version.

[Lorenzo Miniero (lminiero)]

Yep, I did indeed install 1.6 manually to see if the issue was still there, and it seemed like it didn't. It's a pity that Fedora doesn't ship an rpm for 1.6 yet, but it's just a minor inconvenience, as I'm sure they'll do that sooner or later. I did uncover another bug while using 1.6 (occasional crashes when clicking the Edit button), but I'll open a new issue for that as soon as I can gather some data.
