Description of problem:
When opening a new account tab (either manually or automatically during startup) gnucash crashes with the backtrace below.

Reverting from glib2-2.19.2-2.fc11.i386 to glib2-2.18.3-2.fc10.i386 fixes this.
Don't know if this is a glib2 bug or if it can be fixed by simply recompiling gnucash against the new glib2.

Version-Release number of selected component (if applicable):
gnucash-2.2.7-1.fc10.i386

How reproducible:
Always

Steps to Reproduce:
1. Update to new glib2
2. start gnucash
3. open account tab
  
Actual results:
backtrace below

Expected results:
