STR : Reply to an email in english, while default dictonary is set to french (don't know if that matter but that's how I'm currently setup). Hittinf cmd-r will trigger the crash - not always - though.
It has been hit by two users in TB 24.0a1/20130506. It's likely a regression from bug 856270. More reports at: https://crash-stats.mozilla.com/report/list?signature=mozInlineSpellChecker%3A%3AIgnoreWords%28unsigned+short+const**%2C+unsigned+int%29
bp-26d4f6a8-a203-4ef9-9653-b7ba62130606 reply to english email with default dictionary set to english. linux x86_64 had previously noted that the spell check had not displayed the words being checked.
Just in case, here is the regression range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=8f9ba85eb61c&tochange=a47f4e36197f http://hg.mozilla.org/comm-central/pushloghtml?fromchange=1d440abb231f&tochange=d031447ec78b More reports also at: https://crash-stats.mozilla.com/report/list?signature=mozInlineSpellChecker%3A%3AIgnoreWords%28wchar_t+const**%2C+unsigned+int%29

https://tbpl.mozilla.org/?tree=Try&rev=26594cdd6710 IgnoreWords should assert that mSpellCheck is nonnull, like IgnoreWord and related methods do. I probably dropped the ball in not relating bug 856270's spell checker changes to Thunderbird developers. According to mxr it hasn't been updated (And why would it have been? Nobody told them.), which probably explains this: (In reply to Bob Clary [:bc:] from comment #2) > had previously noted that the spell check had not displayed the words being > checked. And it also explains this crash. What probably happened is that SetEnableRealTimeSpell was called as usual, but mSpellCheck now remains null when it finishes. It remains null until nsEditorSpellCheck's async initialization finishes. IgnoreWords must have been called before then. (Other explanations would have meant crashes even before bug 856270 landed.) There's one other site where mSpellCheck is assumed to be nonnull, DoSpellCheck. DoSpellCheck ends up getting called only by ResumeCheck, which returns early if !mSpellCheck, so an assertion in it shouldn't be necessary. However, I added one there anyway as a kind of easily seen precondition. This patch should prevent the crash, but Thunderbird still needs to be updated to account for bug 856270. I'll file a bug for that.
