I moved and deleted a few files that were the data sources for a few layers in a QGIS project. When I re-opened the QGIS project there was a seg. fault. Here are the messages from the terminal:

ERROR 4: `/home/harb/Documents/Varma et al fig 9.png' does not exist in the file system,
and is not recognised as a supported dataset name.

ERROR 4: `/home/harb/Documents/Varma et al fig 7_modified.tif' does not exist in the file system,
and is not recognised as a supported dataset name.

ERROR 4: `/home/harb/Documents/Varma et al fig 9_modified.tif' does not exist in the file system,

I just tested with a vector and a raster and in my case it shows the
usual "handle bad layers" dialog, plus

@
ERROR 4:
`/media/436dc38a-c791-4a29-92e8-1506d42f2a9d/gio/UBC_filipe/dem_move_clipped.tif' does not exist in the file system,
and is not recognised as a supported dataset name.

or

@
ERROR 10: Pointer 'hDS' is NULL in 'OGR_DS_Destroy'.

in the terminal, but no crashes whatsoever.

I'm using qgis 1.8 under ubuntu 12.04 64 bit.

Can you try on another box?

By happy coincidence I've just re-installed my system (not for the purpose of this bug, I needed to for other reasons), and upgraded from Ubuntu Karmic to Precise (12.04). I have installed qgis 1.8.0 from the qgis.org repositories. I continue to get the segmentation fault:

ERROR 4: `/home/harb/Documents/Varma et al fig 9.png' does not exist in the file system,
and is not recognised as a supported dataset name.

ERROR 4: `/home/harb/Documents/Varma et al fig 7_modified.tif' does not exist in the file system,
and is not recognised as a supported dataset name.

ERROR 4: `/home/harb/Documents/Varma et al fig 9_modified.tif' does not exist in the file system,
and is not recognised as a supported dataset name.

ERROR 10: Pointer 'hDS' is NULL in 'OGR_DS_Destroy'.

ERROR 4: `/home/harb/Downloads/meanan/meanann.txt' does not exist in the file system,
and is not recognised as a supported dataset name.

Segmentation fault (core dumped)

Ubuntu's crash reporting system reports a problem with the delimited text provider (or something like that - I can't get it to report anymore, I must have checked the 'don't report this problem anymore' box).
