strange issue with timeUUID columns

Hi,

I am experiencing a strange issue when using TimeUUID as columnkeys.
I am storing a number of events with timeUUId as key in a row. Later I try to query for a slice of that row with a given lower bound timeUUID and upperBoundTimeUUID (constructed as described in the wiki)
If I inserted the events in ascending order everything goes well
If for some reason I insert the events in random order (which may very well happen in a concurrent scenario) and I later query for the data (even with much more tolerant bounds) I get no data back.
Furthermore if I wait for some time (about 15 minutes seem to be sufficient) I can query the data again.
The Cassandra I use is a single node 0.7.0-rc2
I am querying with hector.

Has anyone else experienced such issues?
Can someone think of an explanation for this?

Kind regards,
roland
