Crash while importing footage

Steps to reproduce:
While I usually drag & drop footage into the project bin, I decided to try the Import function.

1. Started new project, Import screen came up

2. Selected files from the folder on my drive array (all silent AVI clips)

3. Import
 
Result: 

1. Nearly all the files on the drive appeared in the bin and on the timeline, including audio files from another project.

2. In the Program window the bit of the screen that was in the Import window (showing the file thunbnails) stayed in the program window.

3. Program becamse unresponsive and crashed when closing
Expected: ... To work!
