[Qgis-developer] python plugins bugs

[Paolo Cavallini]

Hi all.
I am running a course on QGIS, and we stumbled across a few problems 
with python plugins.
64bit machines running Fedora Core crash regularly while running fTools, 
specifically when selecting the file name to save to. This might be 
related to path lenght, but not in an obvious way. 32bit are ok.
Message is:
===
Warning: QgsCoordinateReferenceSystem::findMatchingProj will only work 
if prj acr ellipsoid acr and proj4string are set!...
Segmentation fault
===
Additionally, the regular points utility (under fTools) has apparently 
an encoding problem:
===
An error has occured while executing Python code:

Traceback (most recent call last):
   File "/home/paolo/.qgis/python/plugins/fTools/tools/doRegPoints.py", 
line 76, in accept
     mLayer = self.getMapLayerByName(unicode(inName))
   File "/home/paolo/.qgis/python/plugins/fTools/tools/doRegPoints.py", 
line 188, in getMapLayerByName
     if layer.name() == unicode(myName,'latin1'):
TypeError: decoding Unicode is not supported

Covex hull plugin puts the same ID (the last one) to all polygons, 
instead of the correct ID from the points file.

Split plugin generates incorrect file names (not  the value from the 
variable field, but filename_VARIABLE_<PyQt4.QtCore.QVariant object at 
0x92c3bec>.shp

List unique values seems to add a blank line, thus giving incorrect 
results (N+1).

Mapserver export plugin does not append automatically the extension 
".map" to the file name.

Check geometry validity: the status bar does not work.

Multipart to singlepart and vice versa seem to have inverted names.

ManageR freezes after loading a layer if the projection of a layer is 
not set.

Ready for testing if necessary. Please let me know whether I should open 
tickets for this.
All the best.
