</div>Hi!<br>
I was able to reproduce the error* 10 times out of 10 with the vector<br>
you can download at this link**. Consider that is a "complex" polygon,<br>
but I reproduced the error also with very simple ones.<br>
<br>
These are my observations:<br>
<br>
a) with this test layer (that has many nodes), once clicked with the<br>
"simplify feature" tool, the slider takes a few seconds before show up.<br>
Maybe this is physiological delay, maybe is possible to do something.<br>
<br>
b) add the layer, click with the simplify tool, move the slider, put the<br>
slider to the initial value, click ok -> qgis crashes<br>
<br>
c) add the layer, click with the simplify tool, *don't* move the slider,<br>
click ok -> qgis do not crashes<br>
<br>
then if you click again with the simplify tool, move the slider, put the<br>
slider to the initial value -> qgis do not crashes<br>
<br>
d) when you use the simplify tool as in c), then you exit the editing<br>
mode, qgis asks if you want to save the changes -> this do not make a<br>
lot of sense as no changes were made.<br>
<br>
e) I noticed also the following: take the "majrivers" shapefile (you can<br>
find it in the qgis demo data), and test the simplify tool. On some<br>
features it works fine, on others it behaves like the above description<br>
and on others is enough to click with the tool on the feature to crash<br>
qgis.<br>
<br>
<br>
Platform is Ubuntu 9.04 and QGIS rev. 11005<br>
<br>
<br>
Hope this can help<br>
<br>
