Also, after poking around a bit, I've noticed this only occurs when
trying to add a WPA network, not when connecting to a pre-established
WPA network. I.e. if network-foo was already known by network-manager
before I upgrade network-manager-gnome to 1.8.2, I can still connect and
disconnect without a segfault. It's only when attempting to add the
network that I have the trouble.

Cheers!

Bug#865013: network-manager-gnome: Consistent segfault when connecting to WPA2 network

[Fred Barclay]

Package: network-manager-gnome
Version: 1.4.6-1
Severity: important

Dear Maintainer,
After upgrading network-manager-gnome to 1.8.2-1, the network manager applet
segfaults every time I attempt to connect to a WPA network.

Sample output:
$ nm-applet
Segmentation fault


$ gdb nm-applet

Attempting to dpkg-reconfigure network-manager-gnome and libnma0 had no effect.

Downgrading network-manager-gnome and libnma0 to 1.4.6-1 via `dpkg -i
/var/cache/apt/archives/network-manager-gnome_1.4.6-1_amd64.deb
/var/cache/apt/archives/libnma0_1.4.6-1_amd64.deb`, and restarting nm-applet,
immediately restored the ability to connect to the network.

I've only been able to test on a single WPA network.

Bug#862065: starplot: does not start due to invalid pointer error

[Fred Barclay]

Package: starplot
Version: 0.95.5-8.2
Severity: important

Dear Maintainer,

Starplot doesn't start and returns `*** Error in `starplot': free(): invalid
pointer: 0x55f5759e60d0 ***` when started from terminal.

However, `valgrind starplot` allows starplot to run normally.

This is a completely fresh installation of starplot on a computer that's never
had starplot installed before (so no leftover data in ${HOME}).

Bug#732647: RFP: mintstick -- USB stick formatter

[Fred Barclay]

Package: wnpp
Followup-For: Bug #732647
Owner: Fred Barclay <bugsatef...@gmail.com>

I'd like to bring this to Debian. I'm working on filing an ITP (this is my
first time!) and then hopefully we'll see this in Sid soon.
