QNativeImage: Unable to attach to shared memory segment

[Juan Pablo Caram]

Right after today's automatic update to Ubuntu 14.04, starting FlatCAM yields:

QNativeImage: Unable to attach to shared memory segment.

Rebooting seems to have solved the problem.

[Juan Pablo Caram]

Nope, the problem occurred again. Seems related to Java. Started FlatCAM within PyCharm and the problem happened. Closed PyCharm, started FlatCAM from the terminal and it was okay. Started PyCharm again, FlatCAM was okay both from within PyCharm and the terminal.

Note there was an update to openJDK-7 (Java) this morning.

Not a problem with FlatCAM: http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2015-October/033781.html

I personally downgraded OpenJDK and haven't had the problem again.
