[Bug 511414] [NEW] qt4-designer freeze and crash with long line

[Alan Schneider]

Public bug reported:

$ lsb_release -rd
Description:	Linux Mint 8 Helena - Main Edition
Release:	8

# apt-cache policy qtcreator
qtcreator:
  Installé : 1.2.1-3ubuntu1
  Candidat : 1.2.1-3ubuntu1
 Table de version :
 *** 1.2.1-3ubuntu1 0

I had to manipulate a long line of just less than 1k chars.

When I made cut+paste of this long line, Qt Creator freezed, then crash.
I was forced to "Force quit" the app.
Actually, I *think* the "paste" action made it crash.

>From the command-line I get: "qtcreator.bin: ../../src/xcb_io.c :378 : _XAllocID:  assertion « ret != inval_id » failed."
I don't known if this error is related to this bug or if it prints when "Force quit" is done.

I tried unsuccessfully many times to edit this long line and it always freezed, then crashed.
I had to open my file (.cpp) with another editor to cut the line and continue my work with Qt Creator.
