6941	Crash in X11.XWindowPeer.restoreTransientFor when displaying most basic things	anonymous	team	"What steps will reproduce the problem?
 1. Download anything from OSM
OR
 1. Create an empty data layer
 2. Draw a way
 3. Add a tag, for example ""highway=residential"".

What is the expected result?
 Show the map content

What happens instead?
 After the download, the message ""preparing"" data set appears, followed by a loop of NPEs.
 The problem also occurs after the removal of all plugins. It occurred with rev. 4453 and rev. 4490.

Please provide any additional information below. Attach a screenshot if
possible.
 I have updated my Fedora 15 yesterday. Rev 4453 had worked before the update. The update included kernel-2.6.40.6(=3.0.6), lzo-2.06, exiv2-libs-0.21, php-*-5.3.8 protobuf-2.3.0 and ibus-*-1.4.0.
 The X server (Xorg 1.10.4 with intel_drv 2.15.0) on a GM965/GL960 rev. 3 hardware didn't change during that update.
 However, the error message starts with ""this is always a coding error"", so you should be aware.
