I'm running F11 with Gnote-0.6.2 - compiled from src.rpm from F12 dev repo.


i get a reproducible segfault after following steps:

1- open main ALT+F11
2- the main note contains links to other notes, set the cursor on any of these notes and press CTRL+Enter to open it.
3- close the new note by pressing ESC .
4- try to open it again or any other note by pressing CTRL+Enter.

at this point i get the following in gdb:

Note that this happens only while using Keyboard to navigate into notes, and this is not the case while working with the mouse.

I'm not sure if this is a problem in gtkmm or if this happens with different versions of it.

I remember that i did upgrade from gnote version bundled with Fedora 11 because i had the same problem i think it was 0.4.x .

I'm not sure if somebody already submit this bug before, and if so, i'm so sorry for disturbing.
