Thanks Rubin & David for the replies.
Unfortunately I need Skype, VirtualBox, Oracle JDK
and NVIDIA CUDA Toolkit, I need those many times each day for my work as
a remote developer. I'd love to get rid of Flash, so just now I switched
YouTube to use WebM instead (go to "
http://www.youtube.com/html5") as a start. But when I experience browser crashes, it's not while doing anything strange like watching youtube so I don't think Flash is my problem. Maybe when Dolphin or Plasma or Iceweasel crash it really is a problem with my RAM hardware (I put 16GB RAM in my laptop since i often build Android from source and often use WinXP through VirtualBox), possibly related to the fact I use 5GB of RAM as a ramdisk where I do lots of my temp stuff in.
For the repeatable bugs I found in Kate & Inkscape, you guys convinced me I should file the bug reports and then find ways to live around the bugs for the near future. I sent a message to this group recently about the Kate crash because I wasn't sure how to report it, but no-one replied: "
http://lists.debian.org/debian-kde/2013/06/msg00014.html". For the Inkscape crash i tested it on Mint KDE 14, Mint KDE 13 and ArchLinux and none of those crashed, only Debian Stable, and only while using OpenGL as the KWin renderer (ie: it doesn't crash while using XRender), so I'm also a bit confused about whether to file a bug to Debian or to Inkscape, since it seems to have been fixed in recent versions of Inkscape.
I haven't looked into back-porting packages yet since I read on the Debian FAQ that you shouldn't mix both Stable and Testing in your apt source list, but now I realize back-porting is a way to compile new Testing or SID software packages into the equivalent of Stable packages without modifying my apt sources (or am I wrong?). So from you guys it sounds like I should back-port Inkscape & Skype & NVIDIA driver & CUDA Toolkit, since it is possible that my sudden Plasma crashes or Inkscape crashes are related to the Wheezy's older NVIDIA display driver interacting strangely with Optimus technology (dual GPU).
