Can't install themes (Cydia tries to overwrite)

[RonHC]

Ever since today, I haven't been able to download any themes. I tried both Theme-It and Cydia but both are unsuccessful

Here's the error message
Trying to overwrite `/library/Wallpaper', which is also in package base

Sub-process/usr/bin/dpkg returned an error code (1)

I'm thinking of restoring to iOS 4.2.1 (is that possible since 4.3.2 is already out) and rejailbreak

Any help

Have you saved your SHSH

Have you saved your SHSH

No, but after doing some research, I have found iSHSHit on Cydia
Would you recommend that?

I'm having the same problem... whilst installing themes...
I get the errors:
Trying to overwrite 'library/wallpaper'. which is also in package base
and
Sub-process /usr/bin/dpkg returned an error code(1)
I had a look in library and there wasn't even a wallpaper folder? tried adding one but still the same error occurred?
I vanquish the thought of having to re-jailbreak my phone any suggestions?
