Summary: rkward segfaults R

Initial Comment:
When I try to edit (display) a (my) data.frame within rkward, R segfaults with the following message:

Assert failed at rkvariable.cpp - function getText line 461
output without receiver'
 *** caught segfault ***
address (nil), cause 'memory not mapped'

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

Steps to reproduce:
1. start rkward
2. open my workspace*
3. open the "workspace" tab
4. try to edit the "mydata" data.frame (via right-click -> edit) from my workspace*
5. wait (or click somewhere in the data.frame window)
6. R segfaults

* as the data is personal data of other people I would rather not put it some place with public access.

This happens with a gentoo (rkward-0.4.7) build as well as with a fresh manual build of rkward-0.4.7a.

If you could use further information, do not hesitate to tell me so.

The crash occured in the latest svn version (rev 1921) as well. I will
attach a somewhat stripped (and renamed) version of my data.
File Added: crashy-workspace.r

In the development version of RKWard, I found and fixed some bugs in the
data editor, recently. If possible, could you try, whether you can
reproduce the crash, there
(http://rkward.sourceforge.net/wiki/index.php?title=RKWard_SVN)?

Could you perhaps anonymize the data in some way or another and/or strip
it down to just a few cases (in a way that it still triggers the crash),
and make it available, then? This would help a lot in trying to figure out,
what exactly is going wrong.
