Description Olivier Thomann

2011-01-28 12:50:05 EST

Using eclipse.buildId=I20110126-2200
java.version=1.6.0_24
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=fr_CA
Command-line arguments:  -os win32 -ws win32 -arch x86_64 -console,

I got this exception:

Steps to reproduce:
1) I move the "Progress" view by mistake
2) I wanted to move it back at the bottom of the editor as all other views.

I could not reproduce on another workspace running the same version.

It looks like my workspace is now in a bad state.

Every time I close a new Progress view I get:

This might be a duplicate of bug #320743, the stacktrace looks surprisingly similar.
