Today many Kopete users were faced with an error when they tried to login to the ICQ network. The reported error was that the ICQ version is too old. Bug #165502 describes the problem and Jan provides a workaround in a comment: add the following files to the file
[ICQVersion] Build=0x17AB ClientId=0x010A ClientString=ICQ Client Country=us Lang=en Major=0x0006 Minor=0x0000 Other=0x00007535 Point=0x0000
There have been numerous reports that the fix works on current Kopete versions. Thanks for the fix, Jan!
Additionally the kopete team has updated a ICQ version file which is online and which kopete fetches automatically at startup. This should also fix the problem, without the need to edit or update anything!
