A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

[quickshell] SIGSEGV in QQuickTextPrivate::updateLayout when clipboard contains HTML <img> tagsrevision 1 · captured 2026-10-04 12:03 UTC via poll

What happened

Quickshell crashes with SIGSEGV when opening or updating the clipboard history panel if any clipboard entry contains HTML markup with <img> tags (e.g., rich-text snippets copied from a web browser).

Root cause

In /usr/share/omarchy/shell/plugins/clipboard/Clipboard.qml, the Text items in the list delegate (line 502) and preview pane (line 548) do not specify textFormat: Text.PlainText. Because Qt Quick defaults to Text.AutoText, strings containing HTML tags are parsed as Text.StyledText. When encountering <img> tags with remote URLs or invalid base URLs, QQuickTextPrivate::updateLayout() crashes with a segmentation fault:

WARN qt.quick.styledtext: StyledText - Invalid base url in img tag
#0 0x00007fdc0463e6ef at /usr/lib/libc.so.6
#1 0x00007fdc069172db at /usr/lib/libQt6Quick.so.6

#4 0x00007fdc0698a121 in QQuickItem::setHeight(double) at /usr/lib/libQt6Quick.so.6

Steps to reproduce

  1. Copy an HTML snippet containing an <img> tag (e.g., <meta http-equiv="content-type" content="text/html"><img src="https://example.com/test.jpg">).
  2. Open the clipboard picker / history panel.
  3. Quickshell crashes with SIGSEGV.

### What happened
Quickshell crashes with `SIGSEGV` when opening or updating the clipboard history panel if any clipboard entry contains HTML markup with `<img>` tags (e.g., rich-text snippets copied from a web browser).

### Root cause
In `/usr/share/omarchy/shell/plugins/clipboard/Clipboard.qml`, the `Text` items in the list delegate (line 502) and preview pane (line 548) do not specify `textFormat: Text.PlainText`. Because Qt Quick defaults to `Text.AutoText`, strings containing HTML tags are parsed as `Text.StyledText`. When encountering `<img>` tags with remote URLs or invalid base URLs, `QQuickTextPrivate::updateLayout()` crashes with a segmentation fault:
