Thanks Juan!
It helped that you pasted the error message. I found out the reason.

The scenario is as follows:
- you inserted a field with integer type and set UNSIGNED property true for it
- then you changed that type to TEXT (in general any type that does not support UNSIGNED property)
- upon table creation Kexi adds the UNSIGNED specifier when it's illegal in such case; that's a bug in Kexi

In the case you mentioned the filed name is 'document'. There may be more fields like that, you will find this while saving the design.

Current workaround: 
- temporarily change the type of the problematic field back to integer
- UNSIGNED property will re-appear; set the UNSIGNED property to FALSE
- change the type back to the desired type
- do all the above 3 steps for any other type that has the same problem; to see if you're done just try to save the design

Thanks Juan, that's good news! Have you tried to compile Kexi 3?
Regardless of programming skills bug and wish reporting is welcome. We are
also planning to have distribution-independent Kexi releases.

Cheers.
