Since some time I had some strange issues with the Inkscape (0.48.4) on my machine under Windows. It was dying during startup displaying the "Inkscape encountered an internal error and will close now" message. After reboot the Inkscape usually worked fine, but after starting some other applications it were returning to consequently displaying this error. For example it appeared if the GIMP application was open. To get better understanding of this issue I had run the Inkscape through the gdb. I have found that it crashes on arithmetic exception in "C:\windows\SysWOW64\WinTab32.dll" (called from gdk_display_list_devices in libgdk used by Inkscape's DeviceManager).
Solution: renamed the C:\windows\SysWOW64\WinTab32.dll file to something else...
Remarks: the operation can cause damage to your system, use the "fix" on your own risk
Conclusion: Probably by doing so I have lost some features, but it has fixed the best SVG editor out there :-)
