Summary: rkward crashes or hangs when editing table

Initial Comment:
Hi,

I have encountered a quite severe problem with rkward on my openSuSE 10.3 (64bit). The problem occured the first time after having updated R to 2.7 and rkward to 0.4.9a. I use KDE 3.5.9 "release 60.2". All packages are downloaded from SuSE repos.

How to reproduce:
1) Open rkward with an empty table
2) Change the type of one variable to "string"
3) Enter, say, 4-6 cases by filling in varibles in rows
4) Select one row in the middle and insert a new empty row below the selected row
5) Enter a value in the string variable in the new row and press enter.
At this point rkward either crashes or freezes. I have been able to catch the following error message from the console window:
--- cut here ---
output without receiver'
 *** caught segfault ***
address (nil), cause 'unknown'

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

I have encountered this problem ONLY with data frames having one or more string variables. I have NOT been able to reproduce this with data frames having non-string variables only.

Kind regards,
Kimmo
