Hi together,
in NetBeans 7.3 (Build 201302132200) I'm unable to open regular text/plain-files (see attachement). IDE displays a NullPointerException.

There's no description about where to find logs in the bup reporting guidelines, so I can't provide with more :(

Steps to reproduce: open the attachement using File -> Open file

Expected behavior: file should be opened

Current behavior: nothing happens (exception is indicated)

Thanks in advance for taking care about this.
