Iceape update in Squeeze has erased (?) bookmarks

[AG <computing.account@googlemail.com>]

Today I accepted the update in Squeeze for Iceape.  However, this 
appears to have erased my old/ previous bookmark and password files that 
I used in Iceape before the upgrade.  I have searched through all of the 
relevant dot files and I can't see anything.  Is this standard procedure 
for a browser upgrade to erase files like bookmarks, etc.?  Firefox and 
Opera have never done this, so why would Iceape?  Has Iceape renamed 
them, backed them up somewhere perhaps?

Thus far there is nothing shown through Google on this issue, so 
wondering if anyone else here has come across this and - more critically 
- found a way around it?

Thanks for any assistance before I tear the remainder of my hair out!
