Description nick.dewaide 2014-05-07 22:17:24 UTC
Problem description:
Ctrl + z crashes LibreOffice Writer after ctrl + backspacing letters or words and leading whitespace in front of said letters or words

Steps to reproduce:
1. Type a number of whitespace characters - tabs, spaces, or a combination of the two (NOT NEW LINE CHARACTERS).
2. Type a number of regular characters. For example: "   asdf"
3. Ctrl + Backspace EVERYTHING. The letters/words AND the whitespace characters.
4. Ctrl + Z
5. Should experience "!!br0ken!!" and LibreOffice Writer will crash.

Expected Behavior:
Obviously, you should be able to ctrl + z and get back the characters and their leading whitespace without it crashing. I discovered this upon attemping to format SQL queries in a LibreOffice Writer document.
Operating System: Ubuntu
Version: release

On pc Debian x86-64 with master sources updated today, I don't reproduce this.
But there's another bug that I put in See Also which may prevent to reproduce it.

However, I don't reproduce it too with 4.2 sources updated some days ago.

Could you give a try to brand 4.2.4 LO version?

Hello Nick, *,
I can confirm this bug with

LO Version: Build-ID: 933c0aa564ec4f8883ed5732c866db48dca4dac5
(parallel installed, following the instructions from https://wiki.documentfoundation.org/Installing_in_parallel) with installed Germanophone lang- as well as langpack, but cannot confirm it with

LO Version: Build-ID: 430m0(Build:2)
(Debian's own version)

nor with Version: Build ID: 1baad070d8c2a38581cf33d803c5043f1974647f
TinderBox: Linux-rpm_deb-x86@45-TDF, Branch:master, Time: 2014-11-01_00:19:59
(also parallel installed)

on Debian Testing i686 ... :( As your version ( is rather oldish and is the last released version for the 4.2.x series, would you be so kind to test it with a newer version of LO, please? Does it work for you there?

TIA and have a nice evening
