Crashed when i'm using paint tool

[Chris Guiver (guiverc)]

Thank you for taking the time to report this bug and helping to make Ubuntu better.

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. Using `apport-collect BUGNUMBER` is also an alternative. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Crash reports can be found in /var/crash/ .

You use ` ubuntu-bug /var/crash/[crash-file.crash] ` to submit a crash report.

Please check your /var/crash directory for the crash report and submit it. Please avoid creating a new bug report, but use details (eg. 'Crashed when painting' to search for this report; you likely be offered the chance to search for duplicate) and report as duplicate of this (so detail is added to this report). If it's easier to create a new report then do so, marking this as a duplicate of the new report.

The full crash output is required for bug reports, not snippets, including your details about your release of Ubuntu, desktop used etc.
