1274781 - crash when try to select attachment from file picker and Office 365 installed [@ msoshext.dll@0x7ec1d ]

Status: RESOLVED INVALID

(MailNews Core :: Composition, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Crash reports: https://crash-stats.mozilla.com/signature/?product=Thunderbird&signature=msoshext.dll%400x7ec1d&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&page=1#reports

From an user on IRC: Office 365 updated recently and since then it seems to happen. The user opens the file picker for the attachment and navigates to a folder and then Thunderbird crashes. The crashing msoshext.dll seems to belong to Office 365.

Adding a couple signatures. (But not msoshext.dll@0x30445 for TB31.x which has a different stack)


In general, the whole area of attachments is fraught with issues related to OS and other software, i.e. not Thunderbird :(  https://bugzilla.mozilla.org/buglist.cgi?list_id=13031863&short_desc=crash%20attach&resolution=---&resolution=INVALID&query_format=advanced&short_desc_type=allwordssubstr&product=MailNews%20Core&product=Thunderbird

Closing because no crash reported since 12 weeks.

I haven't checked if this is a match - msoshext.dll | InitializeFileHandlerWithStream is #183 crash
bp-b488425d-3469-4765-aeb4-8feb70190928

Not worth tracking, especially given fair chance we can't do anything.
