Aperture 2 quitting when doing photo edits

Question

I am using Aperture 2 on my Late 2009 27" iMac. OS X 10.9.5 Maverick.
The application quits unexpectedly when making photo edits. (most noticeable if cropping the image). This problem seems to have only recently manifested. I hadn't been doing much editing until today with the new OS.
Is there a compatibility issue with Aperture 2 and Maverick 10.9.5?.
I'm at a loss as my Aperture library is big and I don't know how to move it to a new computer or newer version of Aperture easily.
Is it time to buy a new iMac / Photo edit software?
Thanks

Both your Aperture version and iPhoto version are perfect for working with MacOS X 10.6.8, but nor for your current system. iPhoto 8.1.2 is also incompatible with Mavericks. You should be using iPhoto 9.5.1 for best performance.  with iPhoto 8.1.2 you'll have similar problems.
Could I migrate all my Aperture library to iPhoto easily? It seems that iPhoto has slowed down a lot since I upgraded operating systems from snow leopard to Maverick, thus why I'm hesitant to use iPhoto for editing. I am using an old version of iPhoto however. (09 8.1.2)
Aperture and iPhoto are now compatible and can open each others libraries,but not the older versions you are using. To be able to use both iPhoto and Aperture on the same library you would need to use at least Aperture 3.3 and Photo 3.3., see:  Aperture 3.3: Using a unified photo library with iPhoto and Aperture
For best performance upgrade to Aperture 3.5.1, if you want to continue a professional application, to CaptureOne, or Lightroom. Upgrading to aperture 3 would be the most seamless transit.   If you want to migrate to a simpler application upgrade your iPhoto to 9.5.1, but you would have export your originals and edited versions separately from Aperture.  Upgrading to Aperture 3 would save the lossless workflow.
