baloo_file_extractor crashed with SIGABRT in __gnu_cxx::__verbose_terminate_handler()

[Michael Zanetti]

I have excluded ~ from baloo's indexing folders hoping it would stop eating my CPU cores. That seemed to work fine, but now it crashes every once in a while.

exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

Catch a Xapian::DatabaseModifiedException just in case

The Xapian::WritableDatabase should not be emitting this exception but
bug reports seem to indicate otherwise.

Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Murray (brian-murray)]

This is currently the top reported error about 14.04 on errors.ubuntu.com. It'd be good to get this fix incorporated in Trusty.

[Rohan Garg (rohangarg)]

Will be fixed with the next upload of KDE SC :)

[Rohan Garg (rohangarg)]

Should be fixed with baloo 4.12.97 , please re open if you still have the issue after upgrading.
