Fritzing crashed with SIGSEGV in QMetaObject::activate()

[Logan Rosen]

It is impossible to do anything in Fritzing after closing the update notification. It freezes and then eventually crashes after trying to click anything in the program. This same crash signature appears every time Fritzing crashes.

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

[Logan Rosen (logan)]

This crash is the same as the one reported here in the Fritzing forums: http://fritzing.org/forum/thread/1133/?page=all

It appears to be due to an incompatibility between the version of Fritzing in the Ubuntu/Debian repositories and Qt 4.8.3. An update of the Fritzing package to the latest version upstream will likely solve this issue.

[Logan Rosen (logan)]

Yep, the latest upstream version appears to eliminate this crash, after a quick test of the latest 0.7.10b binary. I have filed a request to update the packaging in Debian at [1], and I have imported that bug to Launchpad in Bug 1077716. After the packaging has been updated, this crash should go away.

[Georges Khaznadar (georgesk)]

The package has been updated (0.8.7b+dfsg-)
