[pca] "Bad patch installed" and "does not match"

[Frank Langelage]

Two questions regarding pca output and patches as of today.

pca in verbose mode says today:

Trying to get rid of the "Bad patch" I get

root at sb2000:/  patchrm 144560-04

...

The following requested patches will not be removed because
they have been made obsolete by other patches already
installed on the system

            0 Patch 144560-04 is obsoleted by 147147-26, which has 
already been installed on the system. It should be removed first.

Is it correct, that 144560-04 is listed as bad patch?
How should I deal with this situation? Remove 147147-26 then 144560-04 
and then reapply 147147-26 again?
