Mac Finder crashing regularly

The Mac in question is;

2011 iMac OS X Yosemite 10.10
Core i5 2.5Ghz Processor
16Gb 1333 MHz DDR3 RAM

I don't normally switch this machine off, and have not really had much in the way of issues with it. However, over the last couple of weeks I'm finding that Finder is regularly crashing, and can be fixed by simply relaunching it. The only way to resolve the issue is to reboot the machine, but within a day or two it will happen again.

It seems to almost always happen after the machine has woke up from a sleep.

One time it happened, I checked the console and found that there were error messages in there about not being able to re-connect to a network share, and put the crash down to that, but today it's happened again and I couldn't see anything of any use in the console.

I've fixed any permissions issues in the Disk Utility, and the S.M.A.R.T status shows as 'Verified'

I am at a loss to figure out what's causing Finder to crash.

Try a Disk Repair and see if that might fix your problems.

For a disk repair you have to start in Recovery Mode by booting while holding down Command-R. Choose Utilities from the menu, then Repair Disk.

If that doesn't fix the problem, try deleting your Finder prefs files:
