            Bug ID: 359494
           Summary: Kfind crashes after never finishing searching the home
                    folder
           Product: kfind
           Version: 2.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: piedro.kulman at googlemail.com

After searching for a name within the content of all files in my home folder -
kfind takes a very long time (many files I guess!) and then crashes in the end
with this message: 

[code]
kfind(13576) KQuery::processQuery: ignoring, not a text file: 
KUrl("file:///home/piedro/VMs/Isoz/linuxmint-17.3-cinnamon-64bit.iso")
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
KCrash: Application 'kfind' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
KCrash: Connect sock_file=/home/piedro/.kde4/socket-arch/kdeinit4__0
[/code]

Now first of all - I do not know why kfind searches within *.iso files and
Virtualbox images... 
this should be avoided somehow (maybe by preference profiles?). 

Why it crashes - I do not know - but looks like a big bug to me. 

Essentially this crashes every search for the content of files. 



Reproducible: Always

Steps to Reproduce:
1. search for a name you know you have in some files in your home folder
2. let it kfind run a long time 
3. wait for it to crash

Actual Results:  
crashes 

Expected Results:  
shouldn't crash

If kfind is to be used within dolphin searches soon - it should not refer to
".kde4" directories, should it?
