Yosemite (10.10) Finder Freezes in Column View In Yosemite (present in 10.10.0 and 10.10.1) Finder regularly and repeatedly (not just randomly) freezes when in column view.

I always use column view by default, so it happens often. It seems to happen when you click on certain file types-- I suspect the "preview" in the right-hand-most pane is causing the problem.


It seems to be related to certain file types (but I haven't figured out which ones yet)
If a specific file type causes a freeze, it always does
If a specific file type doesn't cause a freeze, it never does


For example, if I click on a "zip" file, it successfully generates a "preview" in the right-hand-most pane. Always works. PDF and TXT also work fine.

However, if I click on a ".epub" or ".mobi" file, it always beachballs or freezes Finder. There are other file extensions that also cause freezing, most "non-common" ones seem to do it.

Anyone else experiencing this? Workarounds or fixes?
I was able to resolve my own issue, after finding Quicklook crashing finder in Mavericks:


  Rename/remove the com.apple.quicklook.ui.helper folder in ~/Library/Containers. Logout/in or reboot, and the problem is resolved for me.
