Yes. everybody should have the same problem.
I don't want tu put shame on katipo but...
since version 1.0.0 biblio adding is done like this :
1 ask for a new biblio
2 calculate it's number with max(biblionumber)
3 complete form
4 send datas
5 create biblio (thus incrementing biblionumber in DB).

If you have 2 ppl entering a biblio at the same time... you can have 
twice step 2 before first step 5, resulting in 2 biblios with the same 
number.

/me agree it's an awful bug...

Who want to fix it ? the best being to have an auto_increment field as 
biblionumber that is calculated only at step 5.

Note : the MARC editor don't have this bug (i think/hope/pray :-) )
