GEdit hangs on Autospellcheck

[Jono Bacon]

Binary package hint: gedit

When I open GEdit in Intrepid and switch on autospellcheck (Tools->Autocheck Spelling), it hangs. From what I can tell I have all language libraries installed and switched on correctly.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Backtrace, as per https://wiki.ubuntu.com/Backtrace

[Jono Bacon (jonobacon)]

Sorry, to clarify what I did on the previous backtrace:

 * Started Gedit via gdb
 * Enabled Autospellcheck
 * typed some random text, and pressed the spacebar - then it hung

Hope this helps.

Seb asked me to set the language in Tools->Set Language, and this hangs gedit. Backtrace:

OK, I ran it through valgrind and managed to (a) set the language (this hung before) to United Kingdom, and (b) the auto spellcheck worked (this also hung before). Log is attached.

[Sebastien Bacher (seb128)]

the valgrind log indicates that's a libenchant issue similar to bug #261596

[Jono Bacon (jonobacon)]

Installed libenchant1c2a-dbgsym and ran gedit through valgrind - again setting the language and then enabling autospellcheck and typing in some words. Everything worked. Valgrind log is attached.
