joshua, any smoking gun here?

definitely an uptick in version 14, based on 4 months of crash data.

See also https://bugzilla.mozilla.org/show_bug.cgi?id=315025 --in my case, this has to do with large numbers of group names containing !*,?[\] and other illegal characters.

Tony, I'm a tad unconvinced that fixing bug 315025 will be sufficient for this bug report.  Unless several servers changed around TB14 such that they now have the characters mentioned in 315025.  Or some code change tickled thunderbird to cause the probability of seeing 315025.  

Prior to TB14 the crash rate for this crash signature was near zero - like 1-2 crashes per month per release. And in TB14 several hundred per month per release.

It looked to me like the same "infinite loop" stack. If it isn't, well, un-dupe it. Or as you say, maybe something else (in Tb or in the behaviour new Tb features elicited in users) increased the incidence of bug 315025.

Either un-dupe it now, or wait until one of the two is FIXED, and un-dupe then if it doesn't make the other disappear. You're the Thunderbird man, and in addition I defer to your experience with Mozilla.
