Status changed to 'Confirmed' because the bug affects multiple users.

[Michael Vogt (mvo)]

Thanks for your bugreport.

I can reproduce this with the latest apt/synaptic by:
- opening synaptic
- adding a repository (dosn't crash when removing one)
- clicking on reload, after reload finished and the cache is reopened it crashes in:

RPackage::section (this=0x1658120) at rpackage.cc:111
111 const char *s = _package->Section();

[Fahad (fahadayaz)]

It seems that it crashes when anything in the repository information has changed. If clicking reload and it's still the same (you can tell by the speed), it will not crash.

This is fixed in trunk and it will be part of the next sync.

This bug was fixed in the package synaptic - 0.75.5

---------------
synaptic (0.75.5) unstable; urgency=low

  * common/rpackagelister.cc:
    - simplify openCache() code to use more modern std::vector features
      and fix crash along the way (LP: #936677)
  * common/sections_trans.cc:
    - add "metapackages", "education", "introspection"
  * debian/rules:
    - do not build multiarch support in Debian to make it work on
      unstable that has no multiarch apt yet
