Re: [Shotwell] 100% CPU consumption

As I mentioned in my prior reply, the stack trace isn't useful without Shotwell debug symbols installed.  That would help give me an idea why those calls are being called repeatedly.

Sorry to bother you with this. I'm still experiencing this problem and don't want to lose my Shotwell library. Is there anything else that I can do to help track down the problem? Or do you have any ideas how I could further analyze the problem? Unfortunately, I don't have any experience with Vala development. Thank you.

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.

I will try it when it's ready. Thank you! Titus
