I had 4 crashes in a row,. In each case I received a notification to update to SR-8, but refused or ignored it.
5857.Logos4CrashState.zip
First after/during a metadata update
Second after re-compiling a PB
Third after opening same PB (log overwritten)
Fourth after minimising/maximising the L4 Window (third log).
Things seemed to stabilise after the fifth restart and I updated to SR-8.
