When trying to create convex hulls with settings Create convex hull based on input field, the following error pops up after a few seconds and polygon does not get created:

An error has occured while executing Python code:

Traceback (most recent call last):
File "C:\PROGRA1\QGISCH1\apps\qgis\python\plugins\fTools\tools\doGeoprocessing.py", line 273, in runRangeFromThread
self.progressBar.setRange( range_vals[ 0 ], range_vals[ 1 ] )
TypeError: QProgressBar.setRange(int, int): argument 2 has unexpected type 'long'

Python version:
2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]

QGIS version:
2.4.0-Chugiak Chugiak, 8fdd08a

I have confirmed that with the same dataset and choosing single minimum convex hull, the polygon is created successfully.

I cannot confirm on QGIS master, can you test it? if you still get the same issue please attach sample data.

meanwhile I can confirm that the same tool in the processing toolbox works only if creating a single convex hull, if the option to create different CHs based on an attribute then the output is empty.

The "ftools" category is being removed from the tracker, changing the category of this ticket to "Processing/QGIS" to not leave the category orphaned.
