[SOLVED] Can't rotate images

I am not able to rotate the images in my gallery. I click on the "rotate 90deg counter clockwise" and nothing appears to happen in the browser.

Looking at the server, the request appears to get to the web server (see log entry below) and according to "top" the CPU goes to about 90% wait states for about 30 seconds. The server is noticably slower to respond to other things (eg, ssh) for a short time after attempting to rotate an image.

The only error in /srv/gallery3/var/logs/2013-08-24.log.php is a php timezone not set (which I have since fixed).

OS and browser versions show up in the logs below.

Any suggestions?

Thanks

I just downloaded ImageMagik 6.8.6-8 and compiled it, told gallery to use it, and it hasn't fixed the problem.

I now get the following error in the logfile wen I try to rotate the image...
