Description Brendan Jackman 2012-11-28 16:35:30 EST
Description of problem:
When opening a file from GTK's "recently used files", the following exception is thrown:

Exception in thread "Thread-0" java.lang.NullPointerException
        at sun.awt.X11.GtkFileDialogPeer.setFileInternal(GtkFileDialogPeer.java:79)
        at sun.awt.X11.GtkFileDialogPeer.run(Native Method)
        at sun.awt.X11.GtkFileDialogPeer.showNativeDialog(GtkFileDialogPeer.java:172)
        at sun.awt.X11.GtkFileDialogPeer.access$000(GtkFileDialogPeer.java:39)
        at sun.awt.X11.GtkFileDialogPeer$1.run(GtkFileDialogPeer.java:114)

The user interface stops responding to events (however the application is still redrawn and other threads continue. I'm not sure how to inspect further..

Version-Release number of selected component (if applicable):
Version     : 1.0.1
Release     : 1.fc17

How reproducible:
File >> Open >> Select any file from "recently used files".

Problem persists after reboot and after removing (then re-populating by opening files) ~.local/share/recently-used.xbel. I have attached the contents of that file when it only contains one element.

On my installation arduino reports on launch:

WARNING:  RXTX Version mismatch
        Jar version = RXTX-2.2
        native lib Version = RXTX-2.2pre2
$ yum search rxtx
Version     : 2.2
Release     : 0.6.20100211.fc17.1

(I can't see how that would be related but I have reported it just in case!)

This is really a bug in openjdk, I opened bug #928500 with a patch, let's hope it lands soonish
