Application: kate (3.4.4)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Editing a text file with .csv extension.  Text file has 2280 lines in the format:

FOO
FOO,BAR

There are also some blank lines.  I entered the following search/replace expression to remove the "FOO" lines

Search: [A-Z0-9\-]+\n
Replace: <blank>

Every time I do this Kate crashes.  I am using SC 4.4 from the Kubuntu PPA (10.04 LTS).  This may be related to bu 226409, but none of the reports I saw for that ticket mentioned regular expressions or search/replace. (And I have no way of knowing whether the backported patch for 226409 has made it to the Kubuntu PPA.)  Apologies for the duplicate if this is the case.




The crash can be reproduced every time.
