Description difazio.salvatore 2016-07-03 20:16:54 UTC 
This okteta release turns to be very slow on hex searching. I requires minutes to searching whatever into even not very large files (about 10 M Bytes). The same search once requires few seconds.

Reproducible: Always

Steps to Reproduce:
1. load a binary file of 10 M Bytes or more
2. browser into and select the portion you want to searching for
3. try to look for this file portion

Actual Results:  
It seems okteta hanging so, at the first instance, I kill it after many minutes. Then I re-tried
once more time waiting longer (many minutes) and eventual it finished successfully. 

Expected Results:  
Searching should be, as usual, a matter of few second on these not very large files.

Workaround slowness of search jobs & Co. by buggy QEventDispatcherGlib

For unknown reasons QCoreApplication::processEvents(flag, maxtime) spins
the whole maxtime with QEventDispatcherGlib, something seems broken in
the event processing.
No idea why any QApplication::processEvents were called with a max time
parameter, so simply switching to the variant with no max time, where no
such bug is experienced.
FIXED-IN: 0.20.3
