Re: [Shotwell] 100% CPU consumption

[Jim Nelson <jim yorba org>]

Could you run this with shotwell-dbg installed?  That would help.

Also, I've been fighting a nasty Shotwell regarding caching and Shotwell's memory spiking.  That *could* have some affect here.  Shotwell 0.20.1 will be coming out soon with this patch, so it's worth seeing if that helps.

If you're willing to be more adventurous, you could run Shotwell under gdb. When the CPU spikes, go to gdb and press Ctrl+C, then type bt. That should give you a stack trace. There's a good chance it will show you where Shotwell is spinning its wheels.
