It was a permissions issue, the user wich was running kopete has no access to those files (/opt/kde3/lib/libkopete_msn*) Thanks for your help!!! ckozus.
I'm using Kopete 0.9.2, Suse 9.1 Pro and KDE 3.2.1 When I apply the patch the MSN plugin dissapears (same as Juan_Lutz). If i try to add my msn account again, i get a "msn protocol not found" message. Any ideas ? TIA, ckozus.
