Package: kile
Version: 4:2.1.3-4
Severity: normal

Dear Maintainer,

I am using Debian inside a virtualbox session with a windows host. When working 
on kile projects who are in the virtualbox shared folders, which are mounted at 
(say) /media/vbox_share/, any project within /media/vbox_share/ will hang when 
attempting to close (and thus save) the project. This results in a modest data 
loss, as any information in the project is not saved. The only way I have found 
to resolve the hang is to terminate the process.

This does not occur when saving within the user's home folder.

To reproduce (in virtualbox):
        - Create a new project.
        - Set the project's folder as some sub-folder of a virtualbox shared 
folder. (windows host required?)
        - Close the project
        - Hang.

I do not have problems with other programs accessing files for write.

The resulant backtrace looks like the below - perhaps KLockFile is at fault?:
