cryptkeeper crashed with SIGSEGV in __libc_start_main()

[Alberto Milone]

SRU request:

[Impact]

 * Something must have changed in the gtk+ libraries during Saucy's development
   cycle, thus causing cryptkeeper to segfault when launched. A simple no-change
   rebuild of the package seems to fix it. The package will still fail to launch
   from time to time (as it used to) but it will work fine most of the time.

[Test Case]

 * Enable the the saucy-proposed repository and install cryptkeeper (0.9.5-5.1ubuntu2.1).

 * If cryptkeeper can be launched (in, say, 2 or 3 attempts), then the fix is correct.

[Regression Potential]

 * The regression potential here is zero, as no change is involved.

cryptkeeper (0.9.5-5.1ubuntu3) trusty; urgency=low

  * No change rebuild. It should fix some random segfaults.

Hello Alberto, or anyone else affected,

Accepted cryptkeeper into saucy-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/cryptkeeper/0.9.5-5.1ubuntu2.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Holger (holger-burkhardt)]

The package in proposed workes for me. With regular saucy, cryptkeeper crashed on start, with saucy-proposed, it starts alright! (Though I do not see were I should change the tag to verification-done.....

before:

$ dpkg -l | grep cryptk
ii cryptkeeper 0.9.5-5.1ubuntu2 amd64 EncFS system tray applet for GNOME

after (saucy-proposed):
$ dpkg -l | grep cryptk
ii cryptkeeper 0.9.5-5.1ubuntu2.1 amd64 EncFS system tray applet for GNOME

Still affects 14.04 LTS 64bit.

Please add all possible stale builds from the cryptkeeper sources to this bug!

We're only fine if any binary package is running well.
