Comment (by aperi2007):

 I see it with 1.5.0.

 I can reproduce the bug:

 Open qgis 1.5.0 trunk r13152.
 Add a shapefile in EPSG:3003 (I don't know if it is an epsg-related bug)
 I zoom to a bigger detail (call this "working-extent" for semplicity).
 Now if I add to canvas another shapefile (even the same shapefile 2 times)
 The canvas go automatically to full-extent.
 After add this second layer the  "back" (or last-extent) button is
 disabled, so is impossible to return to the "working extent".
 Of course if I start to zoom the back-button is usable, but is lost the "
 working-extent".

 Perhaps is a bug related to epsg:3003 ?

 Add another hint:
 If I use the 1.0 version of qgis.
 When add the second layer, the canvas go to the full-extent , but the
 back-button is enabled so is possible return immediately to the "working-
 extent".

 qgis 1.4/trunk. I used also data from various sources.
