Bug#587312: glade is *extremely* slow which makes it unusable

[Roland Koebler]

Package: glade
Version: 3.6.7-1
Severity: important


Glade-3 3.6.7 is *extremely* slow:

- Every click on an element in a designed window causes the window to
  blink and Glade to use nealy 1 second of 100% CPU usage.
- Dragging widgets does not work probably; trying to move a label to an
  other table-position took 8 seconds of 100% CPU usage and the label
  ended up in the wrong position.
- Clicking on a spinbutton-button to move an element (e.g. on the "up"
  button of "Packing->Left attachment") takes 4 seconds of 100% CPU
  usage and wrongly increased the value by 2 instead of by 1.
- And much more things which are *extremely* slow

This makes Glade-3 nearly completely unusable for me -- it's impossible
to work with it since you have to wait one or more seconds after every
mouse-click.

AFAIK, older versions (e.g. 3.4.5-3) did not have this problem.

Used CPU: AMD Athlon 64, 2 GHz.
