Comment 35 for bug 91759

@Kohei
I agree with your comments concerning SpreadsheetML support.

Please excuse me, I strongly disagree with your classification of this bug report. The simple rule is:

  Opening a document never causes a crash or a hang.

The report shows a vulnerability of LibO, that can not be accepted. If a user tries to open a unsuspicious looking document with .xls name extensions, and suddenly the program hangs and he looses data of work from last 1/4 hour (or may be even worse), he will think some unfriendly things about LibO

Although it seems that SpreadsheetML are not so often used (it seems I never saw one before), this hang is a major problem.

So I restored Importance.

Please feel free to reassign if this hang problem isn't your area.
