KNotes asked for "migrate now and be patient or lose your data". (What would happen with abort? Would I still be able to migrate later, and how? Dialogue not clear enough.) Ok, rather chose "migrate".

KNotes migrator seemed to run, but then nothing happened. Opening KNotes, the notes were not there. No message about the result. Yikes!

So KNotes did not import notes.

Clicking around, found KNotes collections by chance, activated all of them. The notes came back. (Important notes from 3 years ago about things that progressed in the meantime and still need to be pushed further. Such is the kind of notes I entrusted to knotes!) So far, so good. But is it now ok???

Question now is: What is the status of my notes now? Were they migrated or not? Are they still in some kind of former file format which might get lost later? Or are they were they should be in order to go on from there for later updates? Can I trust knotes from here on and take this problem from my TODO-after-upgrading (to a new kubuntu version)?

What is a collection anyway? (The help, though it's there, doesn't say anything about this. It seems to be from a former version, since the terms do not match those in the GUI and some GUI items are not explained, like these "collections". This might be another bug or two, e.g. GUI-help-mismatch + translation incoherence across versions.)

Why are there so many collections waiting to be activated, what do they contain, where are they located, what is their function?

Knotes is a nice program I liked from the start, but I need to trust it in order to continue to use it, otherwise I'd rather use text files somewhere.

Reproducible: Always

Steps to Reproduce:
1. Upgrade kubuntu.

Did it once, happened every time I did it.
Actual Results:  
No result reported by migrator, which is part of the bug.

Expected Results:  
A message that tells me that migration was successful (or not, in that case indicate steps to repair/migrate successfully).

A way to know the migration status afterwards.

Tell what these collections are and why I would need (or not) each one of them. (This sounds a bit like bug 334142, but may still be different because the collections are there but I don't know where they came from. I have 6 (long+important) notes, but why are there like 15-20 collections?)
