A followup: Also NVIZ is affected
(Image dump -> Max resolution)

can't read "env(GISDBASE)": no such variable
    while executing
"set last_dir $env(GISDBASE)/$env(LOCATION_NAME)/$env(MAPSET)/images"
    (file
"/mpa_sw/ssi/BIO/software/GRASS5.0.0/grass5bin_cvs/grass5/etc/nviz2.2/scripts/fileBrowser.tcl"
line 7)
    invoked from within
"source
/mpa_sw/ssi/BIO/software/GRASS5.0.0/grass5bin_cvs/grass5/etc/nviz2.2/scripts/fileBrowser.tcl"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 $auto_index($name)"
    (procedure "auto_load" line 13)
    invoked from within
"auto_load $name [uplevel 1 {namespace current}]"
    (autoloading "create_file_browser")
    invoked from within
"create_file_browser .file_browser 1"
    invoked from within
".top2.panelarea.menu.file.m.img invoke active"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list $w invoke active]"
    (procedure "tkMenuInvoke" line 47)
    invoked from within
"tkMenuInvoke .top2.panelarea.menu.file.m.img 1
"
    (command bound to event)

It seems we have to search for env(GISDBASE) and other stuff everywhere.
