Bug 309187

Application: kile (2.1.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

find and replace in Kile with a latex document

find pattern ".\n"
replace pattern ". \\ \n"

either with escape sequences or regular expression. Crash occurs only at certain lines, but is reproducible for those lines. Both a single replace or replace all crashes Kile.

It is not possible to provide the document. However the extract below is one place where is occurred (after handled)

"
\begin {itemize}
 \item Unstructured meshes can be read/refined and stored in parallel. \ 
 Different options for partitioning (geometrically with octrees and graph-based) are provided and shared data in refinement is handled.
 \item Chunking of elements is used for optimizing parallel I/O.
 \item An octree is used for generating the chunks.
 The Morton ordering, used for creating the octree, also provides a distribution schema.
\end {itemize}
"

The crash can be reproduced every time.

-- Backtrace:
Application: Kile (kile), signal: Segmentation fault
