ADDITIONAL INFORMATION
Issue reported:
VMware Remote Console (VMRC) 12.0.5 (build 22744838) installed successfully on
Fedora 42 KDE, but when launching “Launch Remote Console” the client crashes
with a core dump. “Launch Web Console” works as expected. Same Fedora version
on GNOME/Xfce desktop environments works without issue.
Evidence
1. ESXi / hostd side (normal MKS session creation):
2025-08-25T09:46:04.120Z info hostd[...] Ticket issued for mks service to user:
vpxuser
2025-08-25T09:46:04.375Z verbose hostd[...] New MKS connection count: 1
...
2025-08-25T09:46:47.087Z verbose hostd[...] New MKS connection count: 0
Hostd shows the ticket was issued and the MKS session was created successfully.
Disconnect occurs only after the VMRC process aborts on the client side.
2. VM log (client connects and later disconnects):

3. VMRC client core dump (Fedora 42 KDE):
#3 Panic_Panic (libvmwarebase.so)
#8 xmlSkipBlankChars (libxml2.so.2)
#10 xmlParseDocument (libxml2.so.2)
#15 gdk_pixbuf_loader_close (libgdk_pixbuf-2.0.so.0)
#20 gdk_pixbuf_new_from_stream_at_scale (libgdk_pixbuf-2.0.so.0)
#23 gtk_icon_info_load_symbolic_for_context (libgtk-3.so.0)
#44 gtk_widget_show (libgtk-3.so.0)
#62 lui::CertificateCheck::ShowDialog (libvmwareui.so)
Stack trace shows VMRC aborts inside libvmwarebase when GTK tries to load a
symbolic icon through the KDE/Breeze theme stack (libxml2 → gdk-pixbuf → gtk).
This occurs when VMRC presents its certificate validation dialog. On Fedora
KDE, the icon theme/loader path causes VMRC to trigger a fatal Panic(). On
GNOME/Xfce (Adwaita theme), the same dialog works fine.
Root Cause
The issue most prbably is on the client OS side (Fedora KDE desktop
environment):
Thus, the failure is environmental and OS/desktop-environment specific.
Conclusion
• Root cause: Client crash due to GTK icon theme handling on Fedora 42 KDE.
• Ownership: OS vendor Fedora/KDE project should be engaged for a permanent
fix.
• VMware software and ESXi host are functioning correctly.
