Problem

This issue is in main branch and also in release version 1.31
I run Fedora 38 6.8.9-100.fc38.x86_64 with tcl8.6 and experience the following errors when trying to open examples/C++/StringList.drn

The program says Error:

File and image width are not identical

Solution

replace bad images/folder.gif file with good file from the sourceforge discussion page I gave in the beginning of my issue

bad file sha256:
e936a17c6a0eba21230644d2ac82d14d801954ea7ad343d90e9ba680f0195cd7 images/folder.gif

good file sha256:
6e8ca09cd1c2449367931f519fa4ab3632bdbdf4f3a66a3f131968a472a2fddf

after this modification program works without flaws.
