Bug ID: 406881
Summary: Infinite loop in sortedPrenodes
Product: korganizer
Version: GIT (master)
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: incidence viewer
Assignee: kdepim-b...@kde.org
Reporter: kf...@kde.org
Target Milestone: ---
STEPS TO REPRODUCE
1. Start korganizer
2. Will hang right after start
OBSERVED RESULT
Hangs in sortedPrenodes() function:
Debugging through the code with breakpoints set reveals the problem: Apparently
there are nodes share the same UID(?) => In that case the while()-loop never
finishes, since it's just overwriting entries in the `prenodeByUid` hash and
thus does not grow.
Trace here:

```
$101 shows that I have "08c6d8f3-a6d4-45a5-af6b-9c08f6cd6638" in there twice.
Shouldn't happen I guess?
Ideas welcome!
