Complete breakdown of pgadmin when trying to connect to server or modify properties of tables of views

Hi there,
On opensuse 10.2 I installed postgresql and pgadmin from the distribution.
Postgresql 8.1.11
pgadmin3 1.6.3
Recently I found that pgadmin didn't work properly: It opened the connection
to the server and to a particular database, I can see the data of the tables
and views but when I tried to modify for example a view pgadmin shut
completely. So I downloaded and installed the last version of pgadmin for my
distribution but it's all the same. In order to be sure that there is no
problem with the older configuration of pgadmin I moved the .pgadmin file so
that pgadmin could create a new one. But with this pgadmin doesn't even
connect to the server, the program shuts down directly.
Starting pgadmin as a normal user in a console I get the error message:
Speicherzugriffsfehler (Segmentation fault)
Doing the same as root I got the following messages:

*** glibc detected *** pgadmin3: munmap_chunk(): invalid pointer: 0x0906a270
***

I must confess that don't have any idea what this means. Therefore I would be
very grateful for any hint about how to make pgadmin work.
Thanks in advance,
