 When I'm trying put scale gadget onto printout layout in "printout
 composer" I get a QGis crash.

 In Qgis 1.0.0/Qt 4.3.1:
 In Linux console I can see comments like these:
 ============================ I'm inserting a new map window
 ==============================
 ======= Qgis does not crash ==========
 Warning: QgsCoordinateReferenceSystem::getRecord failed :  select * from
 tbl_srs where parameters='+proj=tmerc +lat_0=0 +lon_0=19 +k=0.9993

 Warning: QgsCoordinateReferenceSystem::findMatchingProj will only work if
 prj acr ellipsoid acr and proj4string are set!...

 Warning: Object::disconnect: Unexpected null parameter
 Fatal: ASSERT failure in QList<T>::at: "index out of range", file

 --------------------------
 This same I got with Qgis 1.0.1/Qt 4.3.3.
 --------------------------
 In Windows XP Qgis 1.0.1 from OSgeo crashes in this "place" too.
