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.

Sorry for the long delay. I've finally investigated this bug. It was
caused by mishandling of logicals, which are contained in your data.frame.
This should now be fixed in SVN. If you're still around, it would be nice,
if you could give it a try to confirm the bug is fixed
(http://rkward.sourceforge.net/wiki/index.php?title=RKWard_SVN).

(Note: Logicals are still not handled correctly in the data editor, but
should be useable, now)

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.
