Hide Forgot
I have using the currently packaged fritzing-0.9.2b-5.fc24.i686.rpm. It crashes sometimes when editing schematic. New version 0.9.3b works great :)
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
This was reported against a Fedora 24 build of Fritzing (which is EOL) and there's not enough information to identify the problem, so I'm closing this. If it's still an issue with Fedora 26, please open a new ticket with more details about the crash (stack trace, a reproduction recipe, etc).
