Please describe the problem:
after upgrade to gtk 2.6.9 and pango 1.8.2, the editor and related funtionality
(e.g. debugging) is now totally unusable

Steps to reproduce:
1. open any text file
2. 
3. 


Actual results:
most or all all text displayed in editor tabs is grossly mis-spaced and/or
overlaid, moves itself about, and though it is hard to be sure, some of the
content may be omitted

Expected results:
displayed text remains stable, as it used to do

Does this happen every time?
yes

Other information:
noted comments about pango 1.8 in 2.0.x cvs - backport needed ?
