On psppire pspp 1.0.1 on my system:
"Linux MMA-Lenovo-B570e 4.10.0-42-generic #46~16.04.1-Ubuntu SMP Mon Dec 4 15:57:59 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux"
Performing the following steps on /usr/share/pspp/examples/physiology.sav:
1. Data -> Select Cases -> Based on time or case -> Range (any range)
2. Analyze -> Compare Means -> Independent-Samples T Test -> Test variable: Height, Grouping variable: Sex; Define Groups -> Group1: Male, Group2: Female. -> Continue, OK.
3. When I click again on "Analyze -> Compare Means -> Independent-Samples T Test": the test variable appears in non-visible characters, and when clicking "OK" the application terminates with the command line message:
"(psppire:24083): GLib-CRITICAL **: g_string_insert_len: assertion 'len == 0 || val != NULL' failed
Segmentation fault"
Some of my files show rubbish characters instead of non-visible characters, as you can see in the attached image, with the command line message:
"(psppire:24216): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()"
Then clicking OK will also terminate the application.
