I've just uploaded a new KVIrc SVN snapshot (r5829) to Unstable. This one took a little longer than the "normal" ten days because the transition of the previous version waited for some other packages to migrate first. This transition might also take longer than we hope for, due to #625607 in EGLIBC, which leads to a segfault in CMake on SPARC.
The stable update to (more or less) upstream's 4.0.4 is also almost ready. We hope for an upload soon.
