%1 seems to be running on %3. Running %1 and %2 at the same time can cause the loss of mail. You should not start %2 on this computer unless you are sure that %1 is not running on %3.
% 1 semellla estarse a executar en% 3. Executar% 1 e% 2 ao mesmo tempo pode causar a perda de correo. Non debería iniciar% 2 neste ordenador a menos que estea segura/ o de que% 1 non se está a executar en% 3. Start kmail even when another instance is running.
