Crash of boinc-manager upon selection of notices tab with no/bad internet connection

[smoe]

Hello,

I am reporting a crash that is nicely reproducible running boinc client 7.0.28: Try "ifdown eth0" or something else to stop your internet to work, start boincmgr and select the "Notices" tab. Segfault. The CmpNoCase? I presume to be called with a NULL argument, wildly guessing.

When running BOINC on some mobile computer, one is rather likely to experience this problem. Otherwise, well, ... I kindly ask to have a look through those parts anyway since sometimes the BOINC manager just hangs when selecting that tab. But that I could not reliably reproduce that.

Thanks

Steffen

I kindly ask to have a look through those parts anyway since sometimes the BOINC manager just hangs when selecting that tab. But that I could not reliably reproduce that.
