Fwd: crash in Debug::dbgstream ?

Hey guys,

Mikko C. sent me some weird backtrace where an assert in QString is triggered.

Assert is triggered here:
#11 0x00007f9651d39f5b in replaceArgEscapes (s=<value optimized out>, 
d=<value optimized out>, field_width=<value optimized out>, arg=<value 
optimized out>, larg=<value optimized out>, fillChar=...) at 
tools/qstring.cpp:6434

Relevant debug() call in Amarok is here:
#16 0x00007f961524939c in SqlScanResultProcessor::commitTrack 
(this=0x438e1d0, track=0x5f1d5a0, directoryId=3793, albumId=4370) at 
/home/mikko/amarok/src/core-
impl/collections/db/sql/SqlScanResultProcessor.cpp:122

I neither have an idea why it crashes Amarok nor have enough time to 
investigate further.

Please check, might be related to Ralf Engels in-memory stuff.

Hi,
I was rescanning my collection and amarok crashed.
The backtrace indicates an assert in qstring.
