Title:
  LinuxDC++ window never paints; 100% cpu

Status in Linux DC++:
  Expired

Bug description:
  On starting LinuxDC++, I see the main window appear white; it never
  paints. The linuxdcpp process also uses 100% (actually around 150%
  according to top :/ ) CPU. I believe this is different to #966852, as
  I never see the thing load, even if I leave it for days (it's sitting
  on a NAS so can potter away undisturbed by me).

  What's strange, is that it's normally run under user "dcpp". Even if I
  delete the directory /home/dcpp/.dc++, the problem still occurs.
  HOWEVER, if I run it via sux as my day-to-day user "jarrad", it runs
  fine. Copying jarrad's ~/.dc++ over to dcpp's home does not change
  anything.

  I'm running under Debian Testing, and this problem occurs with
  versions from 1.0 up through to current oneiric trunk. I've also tried
  compiling the package from source to no avail. Backtrace below (I left
  about 40 seconds after [Thread 0x7fffed56e700 (LWP 2228) exited]
  before I SIGINTed). It seems to be hanging somewhere in kernel
  threading stuff via gtk - I'm not experienced enough to interpret this
  any further.

  Oprofile shows a vdso from tgid 2220 using the majority of linuxdcpp's time, with main::on() the next.

  Happy to provide more info, but you'll have to walk me through it as
  this is about the limit of my expertise.
