Bug#675249: gedit: Crashes with too high column number given

[Dawid Toton]

Package: gedit
Version: 3.4.2-1
Severity: important

Dear Maintainer,

To reproduce:

echo four >/tmp/four
gedit /tmp/four +1:6

Outcome:

A crash with

(gedit:26206): Gtk-ERROR **: Char offset 5 is off the end of the line
Trace/breakpoint trap

and data loss (changes in all open files in all gedit windows are lost).

My expectation:

The offset shuold be clamped the same way gedit does it for line number.

What led to the situation:

  I call gedit with line numbers and column numbers taken from compiler 
error
messages. It is normal for column numbers to get bit outdated, so I expect
gedit to cope with them in any case.
