pgAdmin III 1.2.2 edit grid crashes with single-column tables

Hello all,
I have got a strange problem with pgAdmin III 1.2.2 on Windows XP SP2. 
I've got a table with only one column (also primary key) of type 
varchar. pgAdmin crashes every time I insert a new row in the edit grid, 
either when hitting enter or pressing the store button. The crash 
actually happens after committing the change. The new data is there when 
I restart pgAdmin.

Can anybody reproduce this?

Regards,
Harald Fricke
