[QScintilla] hotspot error on Linux

[Matic Kukovec]

Hi guys,

I have a PyQt4 application with a QScintilla2 editor with Python3 and 
the following function:
     def create_hotspot(node_tab):
             #Create the hotspot boundaries
             hotspot_line            = node_tab.lines()-2
             hotspot_first_ch     = node_tab.text(hotspot_line).index("-")
             hotspot_length       = node_tab.lineLength(hotspot_line)
             hotspot_start          = 
node_tab.positionFromLineIndex(hotspot_line, hotspot_first_ch)
             hotspot_end            = 
node_tab.positionFromLineIndex(hotspot_line, hotspot_length)
             #Style the hotspot
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_STYLESETHOTSPOT, 
2, True)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETHOTSPOTACTIVEFORE, 
True, 0xff0000)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETHOTSPOTACTIVEUNDERLINE, 
True)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_STARTSTYLING, 
hotspot_start, 31)
node_tab.SendScintilla(PyQt4.Qsci.QsciScintillaBase.SCI_SETSTYLING, 
hotspot_end, 2)    <- ERROR


On Windows this works great, but on Ubuntu this gives me the error at 
the last line with the message:
Assertion [lengthStyle == 0 || (lengthStyle > 0 && lengthStyle + 
position <= style.Length())]
  failed at ../src/CellBuffer.cpp 426


Any ideas?
