Description Roger Pixley 2012-07-20 03:05:46 UTC

Application: krunner (0.1)
KDE Platform Version: 4.8.90 (4.8.90)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Invoking the spell runner with the spell keyword and doing a word longer than 5 letters crashes krunner.

Comment 1 Simeon Bird 2012-10-26 23:29:05 UTC

Git commit 124e35885b8cd1b593b7b83a070bd0bdb5758661 by Simeon Bird.
Committed on 20/10/2012 at 03:16.
Pushed by sbird into branch 'KDE/4.9'.

Fix the plasma spellchecker's 'foreign language' support.
Previously this caused segfaults (even if not used) because
it called setLanguage(), which is not thread-safe, in match().

Instead, this patch constructs a new speller safely for each new
language, without deleting the old one. Old spellers are instead
deleted on the teardown() signal.

While we're at it, amend the language detection so that the user
can type natural language names (eg, 'german') and have the
spell-checker find the right language.
